Description

A kind of method of tea seed shelling
Technical field
The present invention relates to agricultural byproducts processing technical field, particularly a kind of method of tea seed shelling.
Background technology
Oil tea is the distinctive woody oleiferous plants of China, and aboundresources, is of high nutritive value, and has the title of " east sweet oil ".In tea oil, contain abundant unsaturated fatty acids, monounsaturated fatty acids, tea-polyphenol, squalene isoreactivity material, there is the effect that reduces cholesterol, preventing cardiovascular disease and inhibition tumour in blood.For a long time, oil tea is mainly that peasant household is from planting, certainly receive, certainly managing workshop-based oil expression, the hulling method of its tea seed mainly adopts nature suning method, and the time is long, and labour intensity is large, as the rainy weather of long period, also easily produce and go mouldy, affect the quality of tea oil.There are in recent years some mechanical means for tea seed shelling, although can improve shelling efficiency, also easily damaged camellia seed kernel, caused the pollution of follow-up drying process.
Summary of the invention
The object of the present invention is to provide the tea seed hulling method that a kind of husking yield is high, the shelling cycle is short, be suitable for suitability for industrialized production.
The technical solution used in the present invention is the method for a kind of tea seed shelling of invention, comprises the following steps:
A, constant temperature soak:
The preparation of a, soak solution: sodium bicarbonate, salt, bicarbonate of ammonia press to the part by weight mixing of 2-4:1:1-2, added in the warm water of identical weight, 35-50 DEG C, be dissolved into soak solution, for subsequent use;
B, by selected fresh fried flour fruit, according to soak solution: the part by weight of fresh fried flour fruit=1-6:1 is poured into, constant temperature soaks 10-18h, to the fresh fried flour fruit 25-40% that increases weight, the shell of every camellia oleifera fruit is containing sodium bicarbonate 0.05-0.06g, and the shell of every camellia oleifera fruit is containing salt 0.08-0.12g, and the shell of every camellia oleifera fruit is containing bicarbonate of ammonia 0.02-0.05g, become immersion camellia oleifera fruit, for subsequent use;
B, fluidization quick-frozen:
Immersion camellia oleifera fruit for subsequent use is put into fluidization single quick-freezing machine, and quick-frozen 6-14h at-10~0 DEG C, obtains quick-frozen camellia oleifera fruit, for subsequent use;
C, steaming are fried:
Quick-frozen tea fruit for subsequent use is heated to room temperature, then through the dehydration of fluidization fiber desiccant, to touching and soak camellia oleifera fruit surface without moist feeling with hand, pour again temperature into and be the steaming of 80-100 DEG C and fry in container, steam and fry 1-2.5h, be cooled to 35-60 DEG C, steam and fry 1-3h again, must steam and fry tea fruit, for subsequent use;
D, fermentation:
A, fermentation bed preparation:
By following raw material by weight:
Wood chip 10-25 ash charcoal 10-45 insect-proof agent 0.5-3
Unslaked lime 5-25 fine sand 5-10 sanitas 0.1-0.8
Mix, cross 50-70 eye mesh screen, fermentation bed fines; Then, fermentation bed fines is piled into: long × wide × thick is the fermentation bed of 3~5m × 0.5~0.7m × 0.1~0.2m specification, for subsequent use;
B, heap fermentation:
Steaming for subsequent use is fried to tea fruit, be deposited in fermentation bed for subsequent use, pile up by 200-500kg/ ㎡, with the covering of cloth thing, temperature is controlled at 24-40 DEG C, and fermentation 1-2.5 days, screens out fermentation bed fines, obtains shelling tea seed; Separate according to a conventional method again, obtain camellia seed kernel.
Wood chip in described step D is the fine powder being processed from strand by woody section plant or bamboo plant, its moisture content≤2.0%.
The grey charcoal of remainder after Hui Tanshi farmers' calcination plant in described step D, moisture≤1.5%.
Fine sand in described step D is to be pulverized and formed by Wingdale.
Insect-proof agent in described step D is foodstuff insect-proof agent.
Sanitas in described step D is foodstuff sanitas.
The method of tea seed shelling of the present invention, first utilizes water to become ice, and the principle of energy bulked volume makes the inner tension force that produces of oil-tea camellia husks, weakens the tightness of shell weave construction; Recycling sodium bicarbonate and bicarbonate of ammonia are under hot conditions, and reaction voluntarily, produces gas, further weakens shell weave construction tightness, strengthens permeability, is beneficial to follow-up fermentation; Then, utilize the wood chip in fermentation bed, grey charcoal, unslaked lime to absorb the moisture producing in fermentation, effectively controlled fermentation humidity, after unslaked lime water suction simultaneously, energy generating portion heat, accelerates the fermentation of tea fruit, sanitas effectively in stopping fermentation tea fruit rot etc., prevent that tea oil quality from becoming sour.Through test, its husking yield is greater than 90%, and the whole shelling cycle in 5-9 days, the time is shorter, meanwhile, weatherproof, can be suitable for suitability for industrialized production.
