Abstract
The invention discloses a black fungus drying method base on temperature variation. The method comprises steps of preheating a drying room to 30 DEG C, and putting baking trays (6) onto drying partitions (10) in the drying room (7) with the distance among the drying partitions (10) being 20 cm; starting a ventilation fan (12) and ventilating through ventilation holes (11); maintaining the heating rate at 1-3 DEG C per hour; baking at 35 DEG C for 3 h at the constant temperature, and opening moisture exhaust holes or an exhaust fan; raising the temperature, baking at 45 DEG C for 4-5 h at the constant temperature and closing the moisture exhaust holes (8) and the moisture exhaust fan (9) 1-2 hours later; and raising the temperature and baking at 55 DEG C for 1 h at the constant temperature.
Description
Technical field
The present invention relates to crops storage field, particularly a kind of method of the oven dry black fungus based on alternating temperature.
Background technology
Black fungus, as a kind of auxiliary material of the feed of laying hen or broiler chicken, can improve the resistance of chicken, and then improves the survival rate of chicken.And black fungus storage best bet is dried exactly.Hazel mushroom is rich in the nutritional labelings such as a large amount of trace elements, protein, carrotene, vitamin C.The several amino acids that hazel mushroom contains and vitamin, added in the feed of chicken, eats and can strengthen body immunity.Black fungus should toast after sending into drying chamber continuously, until dry, heating can not be interrupted, and temperature can not be fluctuated, otherwise can make the blackening of black fungus color, and quality declines.
Summary of the invention
In order to improve the quality of drying black fungus, the invention provides a kind of method of the oven dry black fungus based on alternating temperature.
Technical scheme: pre-heating drying room temperature is raised to 30 ℃, the oven dry of drip pan (6) being put into hothouse (7) cuts off (10) above, and the spacing of drying partition (10) is 20 centimetres; Opening draught fan (12) ventilates by air vent (11); Heating rate remains on 1 hour and heats 1～3 ℃; 35 ℃ of constant temperature toast 3 hours, open moisture discharging opening or ventilating fan; Heat up, 45 ℃ of constant temperature toast 4～5 hours, and moisture discharging opening (8) and humidity discharging fan were closed after (9) 1～2 hours; Heat up, 55 ℃ of constant temperature toast 1 hour.
Beneficial effect: the black fungus that this method is dried has the peat-reek of black fungus; Complete, do not fall shape; Mushroom body water content is no more than 5%; Black fungus keeps original shape, keeps natural colour.
Accompanying drawing explanation
Fig. 1 is the structural representation of drying plant of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
Pre-heating drying room temperature is raised to 30 ℃, and the oven dry of drip pan (6) being put into hothouse (7) cuts off (10) above, and the spacing of drying partition (10) is 20 centimetres; Opening draught fan (12) ventilates by air vent (11); Heating rate remains on 1 hour and heats 1～3 ℃; 35 ℃ of constant temperature toast 3 hours, open moisture discharging opening or ventilating fan; Heat up, 45 ℃ of constant temperature toast 4～5 hours, and moisture discharging opening (8) and humidity discharging fan were closed after (9) 1～2 hours; Heat up, 55 ℃ of constant temperature toast 1 hour.
