Food waste contains a large amount of water, organic matter, oil, etc., which is easy to corrupt. If it is not treated in time, it is easy to breed bacteria, mosquitoes, flies, etc., and it will also give off odor. Oil is easy to pollute garbage cans on the ground and walls, and it will also seriously affect the ecological environment, Kitchen waste treatment equipment It plays an important role, so let's get to know the principles and process points of kitchen waste disposer together with the kitchen waste disposal equipment manufacturer!

1、 Features and Utilization Value of Kitchen Waste Disposal Machine

1) High water content: 80-90% of the total weight of garbage

2) High content of organic matter: under high temperature conditions, it is easy to corrupt and deteriorate, producing odor

3) Complex ingredients: the main components of fruits and vegetables are vegetable leaves and peel, with high carbohydrate content; Food mainly consists of starch, protein, fat, salt, free fat, etc.

2、 Methods of recycling kitchen and toilet garbage

There are two main methods for recycling food waste: aerobic composting and anaerobic digestion. Aerobic composting process is to use extracellular enzymes secreted by aerobic microorganisms to decompose organic solids into soluble organics, penetrate into cells, and achieve the whole composting process through microbial metabolism. In addition, the same method was derived from aerobic composting. For example, earthworm composting is a new technology developed in recent years. It uses earthworms to swallow a large amount of food waste and mix it with soil, and converts organic matter into nutrients available to itself or other organisms through the mechanical grinding of sandbags and biochemical action in the intestines.

Anaerobic digestion treatment of food waste refers to the microbial degradation of organic waste under specific anaerobic conditions, in which carbon, hydrogen and oxygen are converted into methane and carbon dioxide, and nitrogen, phosphorus, potassium and other elements are retained in the residue for the absorption and utilization of animals and plants

3、 Basic process of kitchen waste processor

1. The collected organic garbage is fed into the pretreatment collection hopper by 120L or 240L organic garbage collector.

2. After screening out plastic, iron, glass and other non organic wastes.

3. The water content in the fruit and vegetable garbage reaches about 50% of that before treatment through equipment crushing, pressing and other processes. After entering the fermentation bin, aerobic microorganisms are added.

4. Set operating parameters, after mixing and stirring, ferment and decompose under the condition of ventilation, heat preservation and oxygen supply, and the temperature rises to 100 ℃.

5. After sterilization, egg reduction, fermentation, deodorization and other processing procedures, the kitchen waste treatment equipment that produces about 10% organic fertilizer can operate automatically for 24 hours.

6. After continuous fermentation and decomposition treatment, 90% of fruit and vegetable wastes are discharged by water, carbon dioxide and bio thermal energy metabolism, and about 10% of organic fertilizer remains after fermentation and decomposition.

4、 Key Points of Temperature Control in Kitchen Waste Treatment Process

When processing food waste resource integration computer, an important link is the biological reaction module (reaction tank). The "enzyme" used there is microorganism - strain. At proper temperature, take time to make it react and conduct organic waste treatment.

5、 At present, there are three main ways to ensure the appropriate reaction temperature of bacteria in the market

1) Direct use of electric heating tube

2) The heated heat transfer oil is jacketed and circulated under the reaction tank;

3) It adopts the form of blowing hot air directly into the reaction tank.

At present, the commonly used intelligent high-temperature heater for the waste treatment industry automatically adjusts the temperature through communication signal PLC optimization calculation to ensure that the temperature is always in the state of fermentation, makes full use of bio heat to achieve biochemical reaction and water evaporation, and effectively shortens the fermentation cycle. The whole process communicates with the upper computer through PLC to realize remote automatic control.
