Method for producing feedstuff coarse albumen powder by kitchen waste

Abstract

A production method fro preparing the feed of crude protein powder with the residues in kitchen is characterized by the steps which comprise selection; smashing; separation; the smashed solid and liquid residue pastes from the kitchen are separated in a centrifugal machine and the oil and water of the separated liquid are separated by a separator; the oil is delivered to an oil tank and the water containing protein is implemented with the step of concentration; concentration; a concentrator is used for concentrating the water containing protein; drying; the concentrated water containing protein is sprayed on the solid paste through a pipe and a nozzle and dried on a drier; the water content is controlled under 15 percent and the feed of crude protein powder is obtained. The processing method is more rational and with the method, the nutrition in residues in kitchen can be fully used and the liquid loss after press filtration is prevented; at the same time, the environmental pollution is prevented or reduced and the production cost is decreased.

Description

technical field

[0001] The invention relates to a production method for preparing feed coarse protein powder from kitchen waste. Background technique

[0002] Kitchen waste refers to food waste and food residues in families, schools, government canteens, and catering industries, and is the main component of municipal solid waste. my country's food waste is large in quantity, high in quality, and mixed, and it is food waste with Chinese characteristics. At present, kitchen waste has become a major public hazard to society.

[0003] If the kitchen waste is not handled properly, it will not only endanger people's health, but also seriously pollute the environment. The moisture content of kitchen waste is as high as 80-90%. The seepage water in swill water can easily pollute the ground water through osmosis. When the temperature is high, the organic matter rich in swill will quickly ferment and rot, resulting in Escherichia coli and other pathogenic microorganisms will direct...

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] A production method for preparing feed coarse protein powder from kitchen waste, the steps of which are as follows:

[0024] (1) Sorting step, sorting the collected food waste on the sorting machine, combined with manual sorting, to remove plastics such as plastic bags, metals such as stainless steel spoons, glasses such as wine glasses, ceramics such as rice bowls, wooden Such as chopsticks and other sundries that cannot be used as feed; in sorting, the exhaust fan can be used to send the odor to the deodorization device for purification treatment, and the treated gas is then discharged;

[0025] (2) The pulverizing step is to send the kitchen waste processed through the sorting step to the pulverizer through a conveyor belt, and pulverize and mix it to form a pasty fluid;

[0026] (3) In the separation step, the kitchen waste crushed...
