Abstract

The invention discloses a tea oil residue hardened paste and an oil pressing method, and can be used for oil residue hardening treatment and oil pressing treatment on oil residue hardened paste in the production process in various large, medium and small production and processing enterprises in tea oil production and processing industry. The technical characteristics are as follows: by utilizing the viscosity of tea oil residues and the adhesion effect principle of oil tea seed husk fragments, the tea oil residues and oil tea seed husk fragments are stirred and mixed to obtain uniform hardened paste, the paste is heated and subjected to extrusion forming, and the paste cake is subjected to oil pressing, so that the oil content of the tea oil residues is reduced from 50% to 5%. The invention overcomes the defects of low oil productivity and poor tea oil quality in the existing tea oil production and processing technique at home and abroad, can be widely used in various large, medium and small tea oil production enterprises, and enhances the oil productivity and tea oil quality.

Description

The tea oil dregs of fat harden big material and oil expression method

Technical field:

The present invention relates to the big material squeezing of hardening of dregs of fat setting treatment and the dregs of fat in a kind of production process of manufacturing and processing enterprise of all kinds of large, medium and small types that can be applicable to tea oil process for processing industry and get the method for oil treatment.

Background technology:

Tea oil is that the diet of eating three meals a day in people's daily life burns a kind of very widely oil plant of use in tasty, the nutritious dish of stir-fry.The manufacturing and processing enterprise that tea oil is all arranged in each area of China is in the process for processing of carrying out tea oil, to satisfy and to enrich the demand in market.At present; Tea oil process for processing technology at home and abroad has hot moulding method for extracting oil and cold press method for extracting oil; Get in the process of manufacture that oil and cold press get oil at hot moulding and to have a large amount of dregs of fat in the crude oil produced, its crude oil accounts for 5% of crude oil greatly through the dregs of fat amount of secondary filter collection.And the oleaginousness in the dregs of fat is 50%, and the dregs of fat are a kind of starchy flowable plastids, and existence can't repeat squeezing and get oil and improve oil yield following three kinds of shortcomings are arranged; A kind of is because the viscosity of the dregs of fat own; In being incorporated into tea seed, repeat squeezing, can't evenly mix, form the ununiformity and the unstable of the soft or hard of raw material; And the press for extracting juice bar slit of oil press zhai can't put in place in instantaneous automatic adjusting, cause in the tea dregs of rice oil length rise with crude oil in the more dregs of fat shortcoming of generation; Two kinds is that the part tea seed increases because of viscosity, pastes with the transport pipe wall, influences tea seed and carries feeding fluency and homogeneity toward oil press zhai, and it is inhomogeneous to cause feeding intake, and forms the shortcoming that sky presses and card presses; Three kinds is that whole tea seed delivery system can't be removed the quality shortcoming that processing produces remaining rotten reduction tea oil owing to mixing the tough dregs of fat.

Summary of the invention:

The objective of the invention is; Squeezing gets that oil yield that oil tech forms is low can't to be improved oil yield again and promote the existing shortcoming of tea oil quality according to domestic and international tea-seed oil, research and develop out a kind of have improve oil yield and the dregs of fat that promote the tea oil quality harden big material and oil expression method.

Technical scheme of the present invention is; These tea oil dregs of fat the harden viscosity and the tea seed shell fragment adhesion effect principle of the big material utilization tea oil dregs of fat; Employing is a synthetic materials by the dregs of fat of 70%-80% and the tea seed shell fragment of 20%-30%; Use whisking appliance that the tea oil dregs of fat and tea seed shell fragment are fully mixed the synthetic big material of the even hardened of processing generation formation; To evenly synthesize the big material of hardened and place in the wooden rice steamer, the wooden rice steamer that will contain big material is again placed heat treated on the steam oven, pours big material in the place mat filter cloth steel ring big material cake of manual extrusion molding then; Oil treatment is got in the oil press zhai squeezing of exerting pressure of packing into of big material cake, be reduced to 5% the dregs of fat harden big material and oil expression method from 50% thereby reach oleaginousness in the tea oil dregs of fat.

Harden big material and oil expression method of this tea oil dregs of fat invented utilization tea oil dregs of fat viscosity and tea seed shell fragment adhesivity effect principle; To adopt the dregs of fat and tea oil seed shell fragment be raw material synthetic technology forms big material processings of sclerosis, big material heat treated, extrusion molding is handled, oil treatment is got in squeezing working method with mixing fully, and this technology has realized improving the oil yield and the lifting tea oil quality characteristics of tea oil seed.

Embodiment:

This tea oil dregs of fat big material that hardens; Its technical characterstic is viscosity and the tea oil seed shell fragment adhesivity effect principle that adopts the tea oil dregs of fat; It adopts dregs of fat weight is the 70%-80% ratio; The fragment specification is that the tea seed shell weight of 3-5 millimeter is the synthesis material of the big material of tea oil dregs of fat hardening for the 20%-30% ratio, fully mixing of whisking appliance and forming.

The harden oil expression method of big material of this tea oil dregs of fat, its technical characterstic are that its adopts the harden heat treated of big material of dregs of fat, and extrusion molding is handled, and the oil expression method of oil treatment is got in squeezing.

The oil expression procedure of the hard big material of these dregs of fat is; Elder generation hardens the tea oil dregs of fat in the wooden rice steamer of being positioned over of big material; Again wooden rice steamer is positioned on the steam oven and heated 10-15 minute; Big material after will heating then is inverted in the steel ring of place mat filter cloth by hand that extrusion molding is big material cake, and with the warm big material cake oil press zhai of packing into, the starting oil press zhai exerts pressure slowly that pressurization rises to high pressure 300-350 kilogram pressure; Make harden tea oil in the big material cake of the dregs of fat flow out the back fully and collect, can release stop oil press zhai work.

Know by above-mentioned; The present invention has adopted the extrusion molding that mixes into the big material processing of even sclerosis, big material heat treated, big material of the tea oil dregs of fat, tea seed shell fragment to handle; The oil expression method of oil treatment is got in the squeezing of big material cake, and the oil yield rate that changes domestic and international existing tea oil process for processing technology is low, the inferior technological method of tea oil; Can extensively be the application of the tea oil manufacturing enterprise of various large, medium and small, types, improve oil yield rate and promote the tea oil quality.
