Description

A kind of method of drying pachyrhizus

Technical field

The present invention relates to crops storage field, particularly a kind of method of drying pachyrhizus.

Background technology

Cancer-resisting substance, abundance of food fiber that pachyrhizus contains the growth of a large amount of sugar, protein, various vitamin and mineral matter, carrotene and vitamin C and inhibition cancer cell, so can Constipation, intestinal cancer; Can reduce the picked-up of heat simultaneously.Pachyrhizus, taste is sweet warm in nature, the defaecation of energy laxation, stomach invigorating benefit gas.Contain more cellulose, can in intestines, absorb the volume of moisture content increase ight soil, cause the effect of defaecation.Brown rice brown rice contains the mineral matters such as rich in protein, starch, vitamin B1, A, E, cellulose, calcium, iron and phosphorus, and wherein abundant cellulosic helps defecation.Mix chicken feed, can improve the cholesterol of eliminating in chicken body, improve the quality of egg or meat.After ground green tea produced in Anhui Province are sent into drying chamber, should toast continuously, until dry, heating can not be interrupted, and temperature can not be fluctuated, and easily quality declines.

Summary of the invention

In order to improve the quality of drying pachyrhizus, the invention provides a kind of method of drying pachyrhizus.

Technical scheme: step 1: pachyrhizus is tanned by the sun 1～2 hour in the sun;

Step 2: pachyrhizus is put into feeding mouth, by the first conveyer belt (1), through dialling bar (8) on the first roller (2), bulk impurity fall into the first roller (2) under be provided with foreign material groove (3); Described the first roller (2) arranges 8 every 4.5 centimetres vertically and dials bar, dials bar for 8 and on average arranges in a plane; Dialling bar length is 8 centimetres; The diameter of the first roller (2) is 8 centimetres;

Step 3: pachyrhizus enters scour trough (4) by the bar of dialling on the first roller (2), scour trough (4) is by top to bottom inclination 30 degree, two sidewalls and the bottom surface of scour trough (4) are evenly distributed delivery port, evenly bath, the shaking device of scour trough (4) bottom surface shakes simultaneously, vibration frequency is 25 times/second, by the impulse force of current and the effect of vibrations, pachyrhizus is slowly by scour trough (4), arrive second roller (5) of the bottom of scour trough (4), after cotton brush being axially set by the second roller (5), pachyrhizus is cut into slices, thickness is 2 centimetres, then enter drip pan (6),

Step 4: pre-heating drying room temperature is raised to 35 ℃, the oven dry of drip pan (6) being put into hothouse (7) cuts off (10) above, and the spacing of drying partition (10) is 40 centimetres; Opening draught fan (12) ventilates by air vent (11); Heating rate remains on 1 hour and heats 1～3 ℃; 45 ℃ of constant temperature toast 5 hours, open moisture discharging opening or ventilating fan; Heat up, 55 ℃ of constant temperature toast 7～9 hours, and moisture discharging opening (8) and humidity discharging fan were closed after (9) 4～5 hours; Heat up, 65 ℃ of constant temperature toast 3 hours.

Beneficial effect: the pachyrhizus water content that this method is dried is no more than 3%; Pachyrhizus keeps original nutriment, 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.

Step 1: pachyrhizus is tanned by the sun 1～2 hour in the sun;

Step 2: pachyrhizus is put into feeding mouth, by the first conveyer belt (1), through dialling bar (8) on the first roller (2), bulk impurity fall into the first roller (2) under be provided with foreign material groove (3); Described the first roller (2) arranges 8 every 4.5 centimetres vertically and dials bar, dials bar for 8 and on average arranges in a plane; Dialling bar length is 8 centimetres; The diameter of the first roller (2) is 8 centimetres;

Step 3: pachyrhizus enters scour trough (4) by the bar of dialling on the first roller (2), scour trough (4) is by top to bottom inclination 30 degree, two sidewalls and the bottom surface of scour trough (4) are evenly distributed delivery port, evenly bath, the shaking device of scour trough (4) bottom surface shakes simultaneously, vibration frequency is 25 times/second, by the impulse force of current and the effect of vibrations, pachyrhizus is slowly by scour trough (4), arrive second roller (5) of the bottom of scour trough (4), after cotton brush being axially set by the second roller (5), pachyrhizus is cut into slices, thickness is 2 centimetres, then enter drip pan (6),

Step 4: pre-heating drying room temperature is raised to 35 ℃, the oven dry of drip pan (6) being put into hothouse (7) cuts off (10) above, and the spacing of drying partition (10) is 40 centimetres; Opening draught fan (12) ventilates by air vent (11); Heating rate remains on 1 hour and heats 1～3 ℃; 45 ℃ of constant temperature toast 5 hours, open moisture discharging opening or ventilating fan; Heat up, 55 ℃ of constant temperature toast 7～9 hours, and moisture discharging opening (8) and humidity discharging fan were closed after (9) 4～5 hours; Heat up, 65 ℃ of constant temperature toast 3 hours.
