Abstract

The invention belongs to the field of biological extraction, relates to a method for producing grease by utilizing pests and particularly relates to a method for extracting grease from barley pests. The method is characterized by comprising the following steps of: airing the barley pests until the water content is below 10%; then, heating the barley pests to 50-70 DEG C; baking the barley pests until the water content is below 3%; adding the baked barley pests into an oil press to squeeze, wherein the temperature of a barrel of the oil press is kept at 90-120 DEG C, and over 60% of grease is squeezed; heating the grease obtained after the squeezing to 120-130 DEG C, and preserving heat for 10-20min; and then cooling to obtain refined grease. The method has the beneficial effects of high oil extraction rate, few impurities, simple treatment process and low investment; the grease can be directly used for replacing fuel oil or used as a chemical raw material; and the grease can be used as high-grade grease after being refined, and the obtained meal can be used as a high-protein feed.

Description

A kind of barley worm is squeezed the method for grease

Technical field

The present invention relates to a kind of method of utilizing insect to produce grease, belong to the biological extraction field, specifically a kind of barley worm method of squeezing grease.

Background technology

The larva of barley worm contains protein, fat, and contains various saccharides, amino acid, VITAMIN, hormone, enzyme and mineral substance phosphorus, iron, potassium, sodium, calcium etc., and nutritive value is considerably beyond insect baits such as fly maggot, earthworm, tenebrio molitor and crickets.

From the comprehensive development and utilization aspect of barley worm larva, the Application and Development of its larva aspect animal protein feed and utilize the edible and nutrient health aspect of barley worm albumen exploitation that relevant report is all arranged, but the Lipid use of barley worm larva research is then less.From assay, contain certain grease in the barley worm larva composition, ripe barley worm larva contains grease 31.2%, the prematurity larva contains grease 27.5%, so the Lipid use of barley worm larva should have certain values, the method utilizes grease to replace the energy, even develops senior grease for medicine, chemical industry, protective foods etc.

Application number is 200610014445.0 to disclose a kind of method of extracting fly maggot oil, and the method adopts extraction, through steps such as sherwood oil lixiviate, Solid-Liquid Separation, underpressure distillation, obtains at last grease.The method operation is more, and must carry out under reduced pressure, operates more loaded down with trivial details; Add man-hour in a large number with an organic solvent, to environment, and sherwood oil is inflammable, body is healthy causes direct harm, and production cost is high; Affect the utility value of grease and crude protein.

Summary of the invention

The present invention overcomes the deficiencies in the prior art, and its purpose is to provide a kind of barley worm to squeeze the method for grease, so that extract worm source property oil technology simplification, economical and practical.

The method that a kind of barley worm of the present invention is squeezed grease, it is characterized in that: with the airing of barley worm to moisture content below 10%, reheat 50～70 ℃, be baked to moisture content below 3%, barley worm after the baking is packed into and squeezes in the oil press zhai, and the oil extruder bore temperature remains on 90～120 ℃, with the squeezing grease more than 60% wherein out, the grease that obtains after the squeezing is heated to 120～130 ℃ and be incubated 10～20min, can obtains polished fat after the cooling.

The method that a kind of barley worm of the present invention is squeezed grease, its specific implementation step technique scheme is:

A. the barley worm live body of cultivation is put into the pond of flowing and cleans scrubbing, removal of impurities, behind 50～70 ℃ of lower baking 3～5min, collecting, again airing to moisture content below 10%;

B. under 50～70 ℃ temperature, again be baked to moisture content below 3%;

C. the screw oil expeller of the barley worm being packed into squeezing, the oil extruder bore temperature remains on 90～100 ℃ during squeezing, carry out twice squeezing. a squeezing of the mat woven of fine bamboo strips is with the squeezing grease of barley worm more than 70% out, obtain grease and grouts, grouts are packed into carry out twice pressing in the screw oil expeller, squeeze again the remaining grease of mountain more than 10%, grouts through flour to 2mm as high protein feed.

D. the grease that obtains can be used as oil fuel and replaces the energy, or with grease after filtration, after the sterilization, use as chemical industry, medical material grease after the packing.

Described squeezing is twice, because barley worm cortex is thicker, and good toughness, destroy relatively difficulty of its cell, thus the screw oil expeller squeezing adopted, for the first time with the squeezing grease of barley worm more than 70% out, for the second time grouts are sent into oil press zhai, with the squeezing grease of remnants out.

Described disinfecting comprise and use charcoal absorption, through decolouring, removal of impurities, deodorizing and filtration, grease is heated to 120～130 ℃ and be incubated 10～20min again, can obtain polished fat after the cooling.

Described grouts flour is to 2mm, as high protein feed.

The method that a kind of barley worm of the present invention is squeezed grease, its beneficial effect is: barley is easily raised by worm, cheap and easy to get, adopt hot pressing press for extracting juice method to be processed into grease, the method is compared with extraction, and oil yield is high, impurity is few, and the non-lubricant component in the grease (unsaponifiables such as phosphatide and VITAMIN) is residual less, avoided dissolvent residual, treatment process is simpler; Technique is simple, less investment, and crude fat content can reach more than 98.3% in the grease that obtains, and this grease can replace oil fuel directly to use, and also can be used for industrial chemicals; Can make senior grease after refining treatment, be used for the aspects such as medicine, chemical industry, protective foods, the gained grouts can be used as high protein feed, utilize the grease that produces to replace the part energy to use.

Embodiment

Following examples further specify the method that a kind of barley worm of the present invention is squeezed grease.

Embodiment 1

Utilize the barley worm to produce the method for grease, may further comprise the steps:

A. the barley worm live body of cultivation is put into the pond of flowing and cleans scrubbing, removal of impurities, behind 70 ℃ of lower baking 5min, collecting, again airing to moisture content below 10%;

B. under 50 ℃ temperature, again be baked to moisture content below 3%;

C. the screw oil expeller of the barley worm being packed into squeezing, because barley worm cortex is thicker, good toughness destroys relatively difficulty of its cell, so adopt the screw oil expeller squeezing, the oil extruder bore temperature remains on 90 ℃ during squeezing, carry out twice squeezing. the mat woven of fine bamboo strips one time squeezing with the squeezing grease of barley worm more than 70% out obtains grease and grouts, grouts is packed into carry out twice pressing in the screw oil expeller, squeeze again the remaining grease of mountain more than 10%, grouts through flour to 2mm as high protein feed.

D. the grease that obtains can be used as oil fuel and replaces the energy, or with grease after filtration, decolouring, removal of impurities, deodorizing and filtration, again grease is heated to 120 ℃ and be incubated 10min, can obtains polished fat after the cooling, use as chemical industry, medical material grease after the packing.
