Problems solved by technology

[0002] At present, it is still in its infancy to process protein powder with deoiled insects in China. Most of them are crushed by ordinary pulverizers, and there is a lot of raw material oil. The fineness of the crushing is difficult to meet the requirements of food and medical protein powder raw materials. Low

Embodiment 1

[0024] see Figure 1-Figure 3 Shown, a kind of method for low-temperature production defatted insect dry pupa protein powder, comprises the steps:

[0025] (1) Clean the fresh and live Tenebrio molitor pupae, and then dry them, wherein the microwave rate is 10kg / KW·h, the temperature is 40°C, and dry until the water content is 9%; then the dried Tenebrio molitor pupae are crushed, and the crushed The dried Tenebrio molitor pupae are put into the rotary conveying extractor, the extraction temperature is 10°C, and liquefied butane is used as the solvent, and the amount added is 6 times of the weight of the Tenebrio molitor dry pupae, and continuous countercurrent extraction is carried out on the dried Tenebrio molitor; wherein, for the rotary conveying extractor, see figure 1 As shown, the rotary conveying extractor includes a vertical rotary conveyor 1 and an oblique rotary conveyor 2, the bottom of the oblique rotary conveyor 2 communicates with the bottom end of the vertical ...

Embodiment 2

[0031] Implementation with reference to embodiment 1, different from embodiment 1 is:

[0032] In step (1), the microwave rate is 12kg / KW·h, the temperature is 45°C, and the drying is performed until the water content is 7%; the extraction temperature is 12°C, and the amount of butane added is 8 times the weight of the dried Tenebrio molitor pupae.

[0033] In step (2), the water content of dried Tenebrio molitor pupae is 7%.

Embodiment 3

[0035] Implementation with reference to embodiment 1, different from embodiment 1 is:

[0036] In step (1), the microwave rate is 15kg / KW·h, the temperature is 50°C, and the drying is performed until the water content is 5%; the extraction temperature is 15°C, and the amount of butane added is 10 times the weight of the dried Tenebrio molitor pupae.

[0037] In step (2), the water content of dried Tenebrio molitor pupae is 5%.

Abstract

The invention discloses a method for producing nonfat dried insect pupa protein powder at a low temperature. The method comprises the following steps that (1) fresh and alive insect pupas are thoroughly cleaned and then dried, then the dried insect pupas are subjected to coarse crushing, the dried insect pupas subjected to coarse crushing are fed into a rotary delivery extractor and subjected to continuous counter-current extraction at the temperature of 10-15 DEG C with liquefied butane as solvent, and afterwards filter residues obtained through extraction of the rotary delivery extractor are nonfat dried insect pupas; and (2) the nonfat dried insect pupas which are dried are delivered into a special pulverizer to be pulverized into the nonfat dried insect pupa protein powder. By means of the method, the residue amount of raw oil is small, the smashing fineness meets the requirement of food-grade protein powder raw materials and medical protein powder raw materials, the quality guarantee period is long, and the economic benefits are high.

Description

technical field [0001] The invention relates to the technical field of deep processing of insect agricultural products, in particular to a method for producing defatted dried insect pupa protein powder at low temperature. Background technique [0002] At present, it is still in its infancy to process protein powder with deoiled insects in China. Most of them are crushed by ordinary pulverizers, and there is a lot of raw material oil. The fineness of the crushing is difficult to meet the requirements of food and medical protein powder raw materials. Low. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to propose a low-temperature production method of degreasing dried insect pupae protein powder which can make the residue of raw material oil low, the crushing fineness meet the requirements of food and medical protein powder raw materials, the shelf life is long and the economic benefit is hig...
