2. Machine Overview

The Eco-Safe Digester® is a high-volume organic waste disposal solution that breaks down food waste into wastewater than can be safely discharged into standard wastewater disposal systems. The Digester uses a highly refined formula of microorganisms to decompose food waste in a short period of time, without odor or pests.

Eco-Safe Digester

The capacity of the machine refers to the average weight of food waste processed in a 24-hour period. It is important to note that while each Eco-Safe Digester model has a standardized maximum capacity specification, capacity can vary based on usage trends and waste content.

Table 1.1. Machine 24-Hour Operational Capacities

Model24-Hour Capacity (lbs)24-Hour Capacity (kg)
Eco-Safe 4800 lbs360 kg
Eco-Safe 81600 lbs725 kg
Eco-Safe 122400 lbs1090 kg


Key Machine Components

The Eco-Safe Digester is comprised of several key components:

Agitator - The agitator is used to aerate the food mixture inside the mixing chamber so that food digestion is effectively maintained. Aerating the food mixture also provides the microorganisms ample amounts of oxygen for optimum performance.

Tower Lamp - The tower lamp provides an easy-to-under stand visual indicator for the status of the machine. For example, when the lamp is lit green, the machine has capacity available for more food. When the tower lamp is lit red, the machine is at full capacity.

Load Cells – A series of four high-resolution load cells continuously weigh the Digester and its contents. Weight tracking allows the machine to monitor its available capacity and is used for weight tracking purposes.

Touchscreen - A friendly, easy-to-use touchscreen allows operators to operate, configure, and monitor the Eco-Safe Digester.

Deodorizer Pump and Mist Nozzles - The deodorizer pump and mist nozzles are used to spray the deodorizer that is stored in the deodorizer tank. A deodorizing mist is activated each time the door is opened or closed. This system is designed to neutralize odor. In addition, it can be set to periodically spray during operation.

High Pressure Washing Pump - There are a series of high pressure washing pump nozzles within the drain discharge area that remove washing oil and fat residues to help prevent blockages in the perforated bottom of the mixing chamber.

Trace Heater - The trace heater controls the temperature of the main chamber. In addition, it heats up the bottom of the machine to prevent oil coagulation.

Integrated Computer System - Each Digester is controlled by a state of the art computer that controls the configuration and operation of the Digester to create the ideal environment for microorganism performance.

Internet Ready - Finally, each Digester is Internet-capable, allowing the machine to send and receive data from BioHiTech Cloud to deliver real-time reporting and remote operational capabilities for end-users.

3. BioHiTech Cloud

Chapter 2. Installation & Start-Up

1. Site Preparation

Please review the requirements outlined in this section before your Digester ships to your location.

Note

All work and costs associated with the site preparation phase are the responsibility of the customer.

1.1. Location

With guidance from the customer, BioHiTechManco recommends a location for the Digester that blends seamlessly into their current workflow and processes. Units are typically placed either at the food waste's point of generation, or its final point of collection.

Easy access to power, water, and drainage aids in determining a unit's location. Finding a location that has adequate and relatively easy access to power, water, and drainage helps minimize site preparation costs.

The location of the Digester should have a level surface.

The optimal space for the machine has at least 3 feet (1 meter) of clearance on both sides of the machine. The additional room is necessary to help facilitate maintenance of the machine.

Appropriate Clearance

Due to the weight and size of the machine, we strongly recommend that these criteria are met. In the event this space is not available, a customer application may be necessary.

See the chart below on the Digester's physical dimensions, based on the model.

The following water requirements must be met:

  • A dedicated warm water source with a 3/4 inch male pipe fitting is also required within 6 feet (2 meters) of the left side of the machine. Incoming water lines should be fully flushed before connection to the Digester.

  • If an extension hose is needed: a 3/4" by 3/4" stainless steel high efficiency hose with a 3/8" inner diameter should be used.

  • Incoming water pressure should be a minimum of 50 PSI (3.5 bars) at 4 gallons (15 liters) per minute.

  • The water source should provide water at 90° to 110° F (32° to 43° C). 
 Some customers may choose to use a mixing valve and a thermometer to ensure a proper temperature.

    Water Mixing Valve

  • The water source should be dedicated to machine operation only. Sharing the water source with other usage is not recommended.

1.4. Drainage

Proper drainage is essential for safe disposal of wastewater from the Digester into the sewer system.

The following drainage requirement must be met:

  • The drain must be an open floor drain and should be connected to the Digester with a minimum 2-inch drain pipe (PVC or Copper). Please minimize any changes in flow direction from the machine to the drain hole. 


    Typical floor drain

  • An elbow fitting should not be used more than 2 times. 


  • A pitch must be maintained at least 1/4-inch declination for every 2 feet length. 


  • If processing large amounts of meat and dairy products, a grease interceptor should be considered. 


2. Transportation

Please review the following guidelines when transporting and leveling your Eco-Safe Digester:

  • Forklift - In the event your machine must be moved with a forklift, be sure to lift it at the base frame between the left and right casters at the bottom of the machine. Extreme caution is necessary to avoid damaging the external cover.

  • Securing with a Bar or Belt - In the event a bar or belt is used to secure the machine during transport, be sure to avoid contact with the top cover of the machine. Use a base frame or caster parts on the lower part of the machine without any excessive force to secure the machine.

  • Short Distance Moves - In short distance moves, a forklift is strongly advised to move the machine after the machine is unloaded. Movement of the machine using the casters may cause excessive vibration that can damage certain electrical components. Movement of the machine using the casters should be avoided at all times except for adjustments to the machine at the final installation location.

  • Leveling - The final location of the machine should be a level surface. The positioning legs will be installed at each corner of the machine and may be used as a level adjuster.

Caution

Excessive vibration or rough handling may cause loosening of machine elements and/or electrical devices, which may impair installation and performance. A qualified service technician should be used for all service and installation requirements.

3. Installation

3.1. Installation Procedure

The following procedure is used to install the Eco-Safe Digester:

  1. Place the Digester in its desired location. Lower the legs.

  2. Connect the power lines into the Digester.

  3. Power on the Digester. Perform a weight test.

  4. Connect the stainless steel drain elbow & PVC tubing as needed.

  5. Connect the warm water source to the Digester.

3.2. Fixed Legs

Roll the Digester to its desired location using its built-in wheels. The final location of the Digester should have a level surface.

  1. Use a bottle jack or pallet jack to raise unit off the floor to enable installation of the stationary legs.

  2. Install the legs. Use a wrench to screw the legs onto the Digester so that they are resting as high as they can go (screwed in all the way).

  3. Use the jack to lower the unit onto its legs. Remove the bottle jack or pallet jack.

  4. Check all four legs. Using a wrench, lower any legs that are not firmly planted on the ground.

For all units:

  1. Legs on both sides of machine must be adjusted all the way down.

    Check to make sure that the Digester is level. Do this by using a wrench to make sure that an equal amount of force is required to turn the screw under each leg. Use a level to ensure that the machine level left-to-right and front-to-back. When complete, lock down the lock nut to make sure it does not move due to vibration.

    Note

    DO NOT use the rocking technique to check to see if the Digester is balanced. There is way too much weight and inertia for this approach.

3.3. Electrical Connection

Chapter 3. Usage

1. How the Digester Works

1.1. Aerobic Digestion

The Eco-Safe Digester uses a process called aerobic digestion to naturally break down organic food waste into wastewater that can be safely discharged into the sanitary sewer system. Since the digested food waste is converted into wastewater, it is natural to use the municipal sewer systems to transport that water to treatment facilities where it will be recovered.

Aerobic digestion uses oxygen and microorganisms to naturally breakdown food waste. Microorganisms are microscopic, living, single-celled organisms called bacteria. Most microorganisms in the world are very beneficial, as they are the housekeepers of the planet; they remove toxins from water and soil and degrade organic matter from dead plants and animals. Without microorganisms, life would be impossible.

Microorganisms perform their work by producing enzymes. Microorganisms are really quite smart – they can detect the organics present in waste and produce only the enzymes that are needed to break down the organics. There are thousands of strains of microorganisms, each with unique characteristics that are important to the organic waste digestion process. BioHiTech partners with companies and industry experts to determine the optimal mix of microorganisms that will breakdown any specific waste profile that your facility may have. Regardless of waste profile, BioHiTech can provide the perfect mix of microorganisms for your application.

The Digester itself provides the optimal environment for the microorganisms to break down food waste. The agitator and paddle arms inside of the Digester constantly aerates the food waste inside of the machine, providing a constant source of oxygen for the microorganisms. Additionally, the Digester uses warm water and a trace heating system, maintaining the correct moisture content and climate for the microorganisms to thrive No grinding or pre-processing of food is necessary for the Digester. The natural aerobic digestion process will breakdown the food.

Enzymes created by microorganisms to breakdown the food particles during the digestion process produce wastewater. As the digestion process continues, these digested food particles become smaller and smaller. When the food particles become small enough, they will pass through the Digester screen, exiting the Digester and into the sanitary sewer system. This wastewater has a greatly reduced organic component, making it safe for discharge. BioHiTech America works to manage and reduce key regulated discharge components, including: Biological Oxygen Demand, Chemical Oxygen Demand, total suspended solids, oils, grease, and pH. BioHiTech America works with you to make sure that all local regulatory requirements are met.

1.2. Digester Features

The Digester provides the optimal environment for the aerobic digestion process to naturally break down food waste. As such, there are many key features of the Digester:

  • Food Habitat - The food habitat inside of the Digester provides an optimal environment of moisture and warmth for aerobic digestion to naturally breakdown food waste. The bottom of the food habitat consists of a screen with small holes. As food waste is broken down, the waste will pass down the holes where it can pass into the sewer system.

    Food Habitat

    Agitator and Paddle Arms - The food habitat also consists of an array of paddle arms. When the food hatch door is closed, the agitator will make the paddle arms rotate inside of the habitat, constantly churning the food waste and introducing the food waste to oxygen. This constant introduction of oxygen is important to the aerobic digestion process.

    Paddle Arm

    Microorganisms - The microorganisms do all of the work to break down the organic content in food waste. Microorganisms are introduced into the Digester through the use of water-soluble packets. They are occasionally replenished.

    Microorganism Packet

    Bio-Media - A collection of specially engineered plastic media is introduced into the Digester at start-up. This media provides an enhanced habitat for the microorganisms. It does not degrade during the digestion process and remains in the habitat.

    Bio-Media

    Tower Lamp - The tower lamp provides a quick visual indicator for the state and capacity of the machine.

    Tower Lamp

    Touchscreen Display - The touchscreen display, located to the right of the food door hatch, provides a detailed machine status. The touchscreen display can be used to operate, manage, and configure the machine.

    Touchscreen

    Showering Nozzles - Inside the top of the food habitat are a series of shower nozzles that routinely spray warm water into the food habitat chamber. This showering feature helps keep the food waste warm and moist, which is an optimal environment for aerobic digestion.

    Washing Nozzles - Underneath the screen of the food habitat are a series of high pressure water nozzles that spray water into the bottom screen of the Digester. These washing nozzles help keep the screen clean as well as the discharge tray in the bottom of the Digester.

    Deodorizer Nozzles - Inside the top of the food habitat are a series of nozzles that spray a light mist of deodorizer solution when the food hatch door is opened. This deodorizer solution is safe, all natural, and will not harm the microorganisms. This light spray helps eliminate any trace odors from the machine when the food hatch door is opened.

    Trace Heater - The a portion of the food habitat is wrapped with an electric heating blanket which helps keep the food contents inside of the Digester warm for aerobic digestion.

2. Feeding the Digester

2.1. Feed Procedure

The following procedure should be use to load organic waste into the Digester:

  1. Check Tower Lamp - Check the tower lamp to ensure that it is okay to place waste into the Digester:

    • If the tower lamp is green, you may feed the machine.

    • If the tower lamp is red, the machine is full and should NOT be fed.

    Tower Lamp

  2. Open Hatch Door - Open the food hatch door by pulling upward on the food hatch door handle.

    Door Handle

  3. Visual Inspection - Perform a quick visual inspection to ensure that the machine is not too full, or contains foreign objects.

    Caution

    If foreign objects are found inside of the Digester, carefully and safely remove them before adding more waste.

    If you are unsure about the safety of removing the objects, please contact your supervisor or contact BioHiTech for assistance.

  4. Load Waste - Load your food waste into the Digester. If placing a large volume of waste into the machine, please note the status of the tower lamp. If the light turns red, stop loading waste into the Digester.

  5. Close Hatch Door - Close the food hatch door firmly. You should hear the food door handle latch, securely closing the hatch.

Once the food hatch door is closed, the Digester will resume its agitation and water cycles to provide the optimal environment for the microorganisms.

2.2. Acceptable Food Waste

Food Types - The general rule of thumb is that the Eco-Safe Digester can consume any organic waste that can be consumed by a human. However, please read and understand the types of materials that may or may not be placed into the Eco-Safe Digester.

Acceptable Food Types

Food Temperature – Items deposited into the Digester should be at room temperature. Avoid throwing in frozen food or very hot foods (like hot soup). Extreme food waste temperatures can have a negative impact on the microorganism habitat, decreasing performance and possibly killing the microorganisms.

Non-Organic Materials - It is important to note that all chemicals, metals, and foreign objects are not suitable for the machine and may cause permanent damage and/or void your warranty.

2.3. Feed Schedule

Ideally, the Digester should be fed every one to four hours. More often (hourly) feeding is preferred. Refer to the table below for optimal feeding sizes.

Table 3.1. Feeding Schedule and Load Size

ModelEco-Safe 4Eco-Safe 8Eco-Safe 12
Daily Capacity800 lbs.1600 lbs.2400 lbs.
Feed Size (every 4 hours)135 lbs.265 lbs.400 lbs.
Feed Size (hourly)35 lbs.65 lbs.100 lbs.


The tower lamp on the Eco-Safe Digester will indicate whether or not the machine can be fed. See the section below for more information about the tower lamp.

Caution

Overloading – The maximum feeding capacity should not exceed the agitator shaft. Do not overload the machine.

Note

Overloading – Oxygen is essential to microorganism performance; overloading the machine will cause the microorganisms to perform inefficiently. Feed scheduling is highly recommended.

2.4. The Tower Lamp

The Eco-Safe Digester continuously monitors its weight. If the weight becomes too high, then the Digester is full and should no longer be fed organic waste. The tower lamp on the back of the machine informs the machine operator of the weight status of the machine.

Please check the status of the tower lamp before placing organic waste into the Digester.

2.5. Best Practices

  • Observe the tower lamp when feeding the Digester. Only add waste when the light is green. If the tower lamp is red, do NOT add more waste.

  • Do not leave the hatch door open for extended periods of time.

  • Feed the Digester frequently throughout the day.

  • A mixed diet containing produce, dairy, bakery items, fish, meat, and poultry should be introduced throughout the day.

  • The smaller the food item size, the better, as digestion will occur at a faster rate. Chopping of larger items such as watermelons and squash is recommended.

  • Avoid adding large quantities of baked goods at one time.

  • Avoid adding frozen items; allow them time to thaw. Food will digest best at room temperature.

  • Keep the machine clean and free from all debris, particularly around the hatch seal area.

  • Make sure that the inside of the machine is hosed off daily. Remove non-organic debris from the inside of the Digester.

  • Refer to the Acceptable Materials decal on the machine for what should and should not be added to this Digester.

  • DO NOT add any cleaning agents, chemicals, or boiling water as they will kill the microorganisms.

  • DO NOT add any cardboard, china, glass, paper, plastic, rubber bands, or silverware as these non-organic items will cause damage to the machine.

  • DO NOT add large meat bones (T-bones, ham ,and shank bones) as they will cause damage to the machine

  • DO NOT add grease, fat, or fryer oil. The Digester is not intended for this purpose.

  • DO NOT hose down the outside of the machine. The touchscreen display must not get wet.

  • Net Mask - The net mask of the network

  • Gateway IP Address - the IP address of the gateway or router on your network

  • DNS Server(s) - the IP address(es) of your DNS server(s). The Digester can accept used to two IP addresses for DNS servers.

Firewall Considerations

The Eco-Safe Digester requires only outbound Internet Access on TCP port 443 (HTTPS, secure HTTP).

Firewalls should be configured to allow outbound Internet access on TCP port 443 to the following IP addresses:

  • 54.221.243.115

  • 54.209.122.209

  • 54.209.181.132

  • 54.208.204.191

  • 54.85.105.167

  • 54.85.142.150

If the BioBrain will be using default external DNS, then the following IP addresses should be allowed outbound Internet access on UDP port 53:

  • 8.8.8.8

  • 8.8.4.4

Optionally, the following IP address can be allowed outbound Internet access on UDP port 4321:

  • 54.85.142.150

Bandwidth Utilization

Average bandwidth utilization is about 3MB per day per Digester.

SSL Proxies

The Eco-Safe Digester does not support SSL/TLS proxy servers at this time.
