Processing equipment and processing technique for poultry feather protein powder

Abstract

The invention relates to processing equipment and a processing technique for poultry feather protein powder, which belongs to the technical field of processing equipment and processing technology for animal derived protein feed, feather powder. The equipment is characterized by comprising a preprocessing system, the preprocessing system is communicated with a hydrolization pressure relief system through a pipeline and a first control valve and also communicated with a vacuum drying system through a pipeline and a second control valve, and both the hydrolization pressure relief system and the vacuum drying system are communicated with a softened water treatment unit. The technique is characterized by including: firstly, dewatering, separating and drying; secondly, relieving hydrolization pressure; thirdly, condensing; fourthly, performing vacuum drying; and fifthly crushing and packaging. The equipment is reasonable in structural design, energy-saving and emission-reducing, environmental harm caused by exhaust emission can be reduced effectively, vacuum drying time is short, drying efficiency is high, using a water cooling tower to timely restore normal operation of the equipment during use guarantees operational time and efficiency of the whole technical flow, and classified emission and treatment for both generated waste water and waste gas are beneficial to environment protection.

Description

[0001] technical field [0002] The invention relates to processing equipment and a processing technology of poultry feather protein powder, and belongs to the technical field of processing equipment and processing technology of animal-derived protein feed feather powder. Background technique [0003] my country has been processing feather powder since the 1980s. The technology at that time was to dry the feathers and put them into iron cages and then put them in high-pressure tanks for high temperature and high pressure. Sulfur Feather Meal. Since the mid-1990s, the hydrolysis method appeared, that is, the wet feathers after slaughtering can be directly put into the tank for processing without drying. It takes a long time, consumes a lot of energy, and the equipment is easily damaged, which is not worth the candle. Gradually after 2,000 years, the method of vacuum drying after hydrolysis has been completely eliminated to process feather powder. After hydrolysis is comple...

Problems solved by technology

[0010] The first kind of production process, because the steam dryer mostly uses the fan to exhaust the steam, the fan will mix the air with the waste steam, which has the disadvantages of large energy consumption, long production cycle, and a large amount of gas that pollutes the environment

[0011] The second production process has the disadvantages of high energy consumption, high ash content of finished products, poor quality, and a large amount of gas that pollutes the environment because the direct fire dryer uses a fan to exhaust steam, and the fan will mix air with waste steam.

[0012] The third production process has the disadvantages of large energy consumption, long drying time, low drying efficiency, and the generation of gas that pollutes the environment.

[0013] The fourth production process has the disadvantages of high energy consumption, long drying time, low drying efficiency, and a large amount of gas that pollutes the environment because the heat transfer oil dryer uses a fan to exhaust steam, and the fan will mix the air with the waste steam.
