Abstract
The invention relates to a tremella fuciformis drying process. The drying process is characterized by comprising the following steps of: 1) cleaning tremella fuciformis, putting the tremella fuciformis in dishes, draining water in the tremella fuciformis and feeding the tremella fuciformis into lifting cages in a dryer from a side door at the front end of a drying cabinet, wherein each lifting cage accommodates a plurality of dishes of tremella fuciformis; 2) conveying the lifting cages by using a double-chain conveyor, keeping the outlet temperature of a warm-air pipe during drying be 80 DEGC, and drying the tremella fuciformis with vertical airstreams of the warm-air pipe, wherein a period is calculated from the feeding of one dish of tremella fuciformis into the dryer to the drying ofthe tremella fuciformis until the tremella fuciformis has a water ratio of less than or equal to 8 percent; and a programmable logic controller (PLC) program is used for controlling the drying process by adjusting the running speed of chains, and monitoring the temperature and humidity of a wet and dry bulb meter at the same time; 3) discharging the dried tremella fuciformis out of a furnace fromone side of the side door at the front end and feeding new tremella fuciformis at the same time to start the drying process in another period; and 4) conveying the finished products to a workshop fordetection, grading and packaging. The process has the advantages of achieving nontoxic and aseptic production easily, reducing pollution and the rate of damage caused by manual contact, effectively increasing the output of the tremella fuciformis, saving occupied area and reducing energy consumption.
Description
Technical field
The present invention relates to a kind of tremella fuciformis drying process and drying unit thereof.
Background technology
Fujian Province's Gutian County is " township of edible fungi of china " of having won fame both at home and abroad.1995,1997 liang of titles of honour of year being authorized " township of edible mushroom " by units such as State Council centre of development, the Ministry of Agriculture.340,000 tons of fresh goods of edible mushroom gross annual output amount are the first in the nation, and wherein white fungus accounts for 50% (volume of production and marketing all ranks first in the world), and mushroom accounts for 25%, and other mushrooms account for 25%.Gutian County mushroom, dictyophora phalloidea, white fungus are won one, two Chinese agriculture fair gold medal.1999 " Gutian white fungus " is again by " best brand of product is regarded as in 99 Chinese International Agriculture fairs, is chosen as famous agricultural product brand by Fujian Province government in 2000.
The white fungus drying technics is different from other food and pharmaceuticals.Generally should select diameter to reach 8-12cm, the bright white fungus of fresh weight 100-200 grammes per square metre, one Duo-Duo is arranged on the baking sieve, can not be overlapping in order to avoid adhesion, be that process temperature processed should be controlled between 70 ℃-80 ℃, strengthen simultaneously hydrofuge, its root is difficult doing, and whole is dried to moisture content and is lower than 8% need maintenance 8-10 hour.Existing vacuum drying and the vacuum freeze drying that is widely used in other food and pharmaceuticals directly applies to the white fungus drying without transformation, be difficult to overcome drying time long, because installed power is larger, the shortcoming that energy consumption is higher.
The existing white fungus drying means that accounts for main flow in Gutian, as the main workshop-based baking room of edible mushroom take dry white fungus,, its structure is that the brick body is steamer-like: separate room drying chamber 2m is high, 1m is long, the wide built-in multilayer screen tray of 0.8m (80cm * 100cm), form again 1 row's baking room between every 10-15; Configuration heater and hot-flow flue pass to the drying chamber bottom, and installation shaft flow type fan under screen tray (the general 1.0kw of power of motor) upward type ventilates, and row's method on the nature is adopted in exhaust.Its oven dry finished product type is better.Yield poorly but also exist, drying time, longer energy consumption was large, the defective of product drying inequality: reason is that vertical hot blast penetrability is poor, and the white fungus drying of the abundant stacking of multilayer high-moisture percentage is caused the larger gradation of moisture and thermograde from bottom to top.When the hot blast initial temperature kept 80 ℃, 6-8 hour lower floor dried by the fire moisture content and has been lower than 8%, and the superiors' temperature still is lower than 50-60 ℃, and moisture content is still up to more than 50%.Therefore, needing manually will the most lower 2 layers of upset and frame, and the upper strata is successively turned down, and puts into new material top again.Not only the omnidistance oven dry cycle longer, and transfer frame workload and thermal loss large, the breakage rate of 1.5-2% is arranged.
Summary of the invention
The object of the present invention is to provide a kind of tremella fuciformis drying process, this technique is a kind of process for cleanly preparing of low temperature drying white fungus, easily realize nontoxic asepticize production, reduce artificial contact damage rate and pollution, compare with the workshop-based baking room of traditional edible mushroom, under same consumption energy, improve production capacity 100%, saving occupation of land and reduce the thing energy consumption more than 50%, be particularly useful for the dry production of white fungus industrially scalable.
