Abstract
The invention discloses a lepidium meyenii walp temperature-varied drying method and belongs to the technical field of preliminary processing of agricultural products. The method mainly comprises the following steps of cleaning and washing fresh lepidium meyenii walp, draining off water residues on the lepidium meyenii walp, and conducting temperature-varied drying on the lepidium meyenii walp at the room temperature. Compared with a traditional airing method, according to the method, hot-air drying equipment is used, the process that the temperature is raised gradually from the low temperature to the high temperature at a variable-speed mode is adopted, lepidium meyenii walp moisture is prevented from being lost rapidly, shape change is reduced, the color and lustre are maintained, under the condition that nutritional ingredients are not lost, the lepidium meyenii walp drying time is shortened by over 20 days, the drying efficiency is remarkably improved, and meanwhile defects that by means of a traditional solarization method, manpower is consumed, the occupied area is large, and pollution is prone to occurring are avoided.
Description
Technical field
The invention discloses a kind of agate coffee alternating temperature drying means, belong to agricultural product Primary processing technology field.
Background technology
Agate coffee (
lepidiummeyenii) belong to Cruciferae separate row Vegetable spp (
lepidium), calling as beet root or Peru's ginseng, is the plant of dietotherapeutic.Have and strengthen the effect such as muscle power, enhancing body immunity, antifatigue, raising fertility.2011, pueraria root powder was formally approved as new resource food through former health ministry.The agate coffee planting base of China more than 60% concentrates on Lijing, and Annual planting area and the output of this area's agate coffee reach 175hm respectively
2and 780t, occupy 90% and 93% of the whole nation, the Lijing agate coffee output value of 2014, close to 4,000,000,000, has become local farmers Important Economic source.
Current agate coffee generally adopts the drying mode of airing, this technological process for gathering → washing → prune away hair root (block root is cut into slices by the area had) → naturally dry.This drying mode is simple to operate, with low cost, but deposits many deficiencies.First, consuming time longer, usually will at more than 30d, production efficiency is lower, and the amount of labour used is large.Secondly, sanitary condition is poor.Shine canopy, threshing ground to be even difficult to stop the pollutions such as worm, mouse, dirt in the airing place such as garden.Again, naturally drying agate coffee affects by different places aerial temperature and humidity, and outward appearance and inherent quality differ greatly.Therefore, introducing efficiency drying equipment that is high, easy to operate, small investment, also to set up the drying process adapted with it of crucial importance to agate coffee drying cost-saving synergistic.
Fresh agate coffee is processed into dry products by utilizing room temperature draining and alternating temperature dry technology by the present invention.
Summary of the invention
The object of the present invention is to provide a kind of agate coffee alternating temperature drying means, adopt alternating temperature dry technology, fresh agate coffee is processed into dry products, significantly shortens process time, and stopped the pollution of worm, mouse, dirt etc.
Object of the present invention is achieved by following technical proposals:
(1) naturally drain to surface without moisture under the fresh agate coffee cleaned being positioned over room temperature;
(2) the agate coffee obtained in step (1) is carried out drying by alternating temperature drying mode, until reach moisture content≤13%.
The detailed process of described alternating temperature drying mode is initial drying temperature is 20-30 DEG C, this temperature by the programming rate of 2.5-5 DEG C/24h, is evenly warming up to 55 DEG C after keeping 30-40h, after being evenly warming up to 65-70 DEG C with the speed of 5-10 DEG C/12h again, insulation is until agate coffee moisture content≤13%.
Beneficial effect of the present invention is:
(1) agate coffee drying means of the present invention is compared with traditional airing method, adopt alternating temperature drying mode, and baking temperature from low to high, slowly heats up; The early stage of drying low temperature avoids sharply scattering and disappearing of agate coffee moisture, thus decreases the fold degree of agate coffee epidermis, and the later stage of drying high temperature decreases the degraded of nutritional labeling;
(2) agate coffee drying means of the present invention shortens more than 20 days time than traditional airing method;
(3) the dry agate coffee of the method for the invention is while its mode of appearance of guarantee and inherent quality, it also avoid the deficiency such as conventional method labor intensive, large, the easy pollution of occupied ground.

Detailed description of the invention
Set forth substantive distinguishing features of the present invention and significant progress further below by embodiment and accompanying drawing, but protection scope of the present invention is absolutely not only confined to embodiment.
Embodiment 1
New foresythia agate coffee is cleaned, naturally drains under being positioned over room temperature to surface without moisture; Then be placed in Chinese medicine and be placed in hot air drier drying; Technological parameter is, is under the condition of 30 DEG C after steady temperature 40h, after being evenly warming up to 55 DEG C, is more evenly warming up to 70 DEG C with the speed of 10 DEG C/12h by the programming rate of 5 DEG C/24h in initial temperature, and insulation is until dry, and the time reaching moisture content≤13% is 130h.Agate coffee surfacing corrugationless after dry, overall deformation is little, its apparent lovely luster (see Fig. 1,2,3).
Embodiment 2
Fresh purple agate coffee is cleaned, naturally drains under being positioned over room temperature to surface without moisture; Then be placed in Chinese medicine dryer and dry; Technological parameter is, is under the condition of 25 DEG C after steady temperature 35h, after being evenly warming up to 55 DEG C, is more evenly warming up to 65 DEG C with the speed of 7.5 DEG C/12h by the programming rate of 3 DEG C/24h in initial temperature, and insulation is until dry, and the time reaching moisture content≤13% is 118h.After dry, agate coffee is bright-colored, surfacing corrugationless, overall deformation little (see Fig. 4,5).
Embodiment 3
Fresh black agate coffee is cleaned, naturally drains under being positioned over room temperature to surface without moisture; Then be placed in Chinese medicine dryer and dry; Technological parameter is, is under the condition of 20 DEG C after steady temperature 30h, after being evenly warming up to 55 DEG C, is more evenly warming up to 68 DEG C with the speed of 5 DEG C/12h by the programming rate of 2.5 DEG C/24h in initial temperature, and insulation is until dry, and the time reaching moisture content≤13% is 123h.After dry, agate coffee appearance luster is better, surfacing corrugationless, overall deformation little (see Fig. 6,7).
