Description

Lotus seeds electrical heating rotary drying device
Technical field
It is big that the present invention relates to a kind of graininess, thermal sensitivity agricultural product electrical heating rotary drying device more particularly to lotus seeds etc. The lotus seeds electrical heating rotary drying device of granule materials.
Background technology
Lotus seeds are China's Ways of Special Agricultural Products, are loved by consumers.Drying is the important means of dry lotus seeds processing.Lotus seeds Grain is big, and content of starch is high.Unsuitable drying easily causes lotus seeds hardening, drying time extends, and influences product quality and drying Efficiency.Traditional dry lotus seeds production method is mainly dried using charcoal fire baking or the sun.The sun, which dries, easily to be influenced by weather, is given birth to Object pollutes, and time-consuming;Drying process easily makes the polyphenols in lotus seeds aoxidize, and product is caused to black;Charcoal fire roasting mode The disadvantage is that the duration and degree of heating is difficult to control, take a lot of work more, it is easy scalding, burned, seriously affect product quality.In recent years, with hot air convective drying, micro- Novel lotus seeds dry technology based on wave drying is rising.Lotus seeds particle is big, the hot air convective drying later stage its internal moisture not It easily removes, drying time is long;The microwave drying time is short, but the inhomogeneities of microwave distribution is easy to cause lotus seeds hot-spot, coke Change.
From the point of view of heat transfer type, drying can be divided into the modes such as conduction, convection current, radiation and micro-wave dielectric.Conductive drying is Material is directly effectively contacted by dry process with heating surface, and heat-transfer mechanism is based on heat transfer.Compared to present extensive use Convective drying technology, conductive drying remarkable advantage is that heat and mass is efficient, the thermal efficiency is high.Former is mainly that rotating cylinder is dry Dry machine, rotary drum dryer etc., application field is extensive.It is widely used in numerous graininess such as chemical industry, medicine by many countries In the drying field of material.This kind of drying equipment heat source is mainly based on steam or hot-blast stove heating, and drying temperature is high, and temperature is not It is easy to control, be not suitable for the drying of the granule materials such as thermal sensitivity lotus seeds.
Conduction type whizzer operation principle is that raw material enters from drying cylinder one end, when by cylinder interior, in cylinder Heating surface is in direct contact and is dried, and the product after drying is collected from the other end.Inner barrel is equipped with shovelling plate, material can be made to raise It rises, under throwing, material is made to be come into full contact with heating surface, improve rate of drying.
Based on conductive drying technology, the controllable drying equipment of exploitation drying condition can be that the bulky grains agricultural product such as lotus seeds add Work provides a kind of new drying method.It is had not been reported using the drying device of electrical heating rotary drying lotus seeds.
Invention content
In view of the above-mentioned problems, an object of the present disclosure is to provide lotus seeds electrical heating rotary drying device, electrical heating rotating cylinder Drying device is in direct contact using rotation electric heating tube to dry lotus seeds, and interior dry drum outer wall is close to electrothermal tube or winding electricity adds Lotus seeds high quality heat conductive drying is realized in the torrid zone.
The object of the invention second is that electrothermal tube or heat tape use temperature controller temperature control, realize drying device constant temperature, After setting drying temperature, temperature controller realizes drying cylinder heating, cooling by controlling relay on-off, meets drying Technological requirement.
The three of the object of the invention are to extend lotus seeds in drying using drying cylinder positive and negative rotation, the interior method for setting helical form shovelling plate Residence time in cylinder realizes lotus seeds evenly drying.
