Description

Process and device for producing feed from food waste

The present invention is to provide a process and apparatus that can feed various foods through a process such as pressing, steaming, drying, cooling, foreign matter screening, and the like, and particularly relates to a feed process and apparatus suitable for a large capacity.

Normally, the remaining foods after meals are classified as non-recyclable waste and disposed of and disposed of, causing various environmental pollution. However, in recent years, various methods of recycling such leftover foods as fermented feed have been devised. .

However, the existing food processing device is made of semi-auto (semi auto) method, and the development of an automatic device was required.In the process of food processing, foreign substances were removed manually by inputting the main body, and artificial rice bran, wheat flour, etc. It is produced by mixing the moisture control agent and fermentation agent, so it is expensive to add additives and is classified as a compound feed rather than a sweet food, which produces a low level of unbalanced feed and pollutes the surrounding air because it cannot deodorize odor generated during processing. In addition, there was a problem that the absorption rate is reduced when used as a fermented feed can not effectively destroy the fiber in the food waste.

In order to solve the problems of the conventional food treatment apparatus described above, the inventor of the present invention has already filed an application (application number: 10-1999-0020156) with respect to the food feed process and apparatus. In the remaining food processing process where waste gas generated in the self-cooking process and waste gas generated during the treatment process is exhausted to the outside via the cooling unit and the deodorizing unit, the remaining food to be treated is sterilized, hydrolyzed and dried in the double disc feeder. After discharging at the same time, it is discharged at once and stored in an intermediate storage tank and transferred to a cooling drive. The double disc feeder is subjected to a new raw material to be sterilized, hydrolyzed and dried at the same time. The finished sweet rice feed from the disc feeder to the drying operation has a grinder and a foreign substance. One was going to be transferred to the cooling device is configured with a dry-to-market by cooling, crushing and removing the metallic foreign substance in the magnetic separator.

However, the above-described application and the like are related to a small process and apparatus capable of processing foods, usually less than about 24 h / 30t, and thus have a problem of continuously processing a large amount of food.

Accordingly, the present invention has completed the present invention with the technical problem of the present invention to provide a large-scale food continuous processing process and processing apparatus that can eliminate the problems with the conventional food feed apparatus and process as described above.
