Description
Technical field
The utility model is meant a kind of low-temperature drier of two-period form control especially about a kind of two-period form low-temperature drier.
Background technology
Known cryospray drying solid-liquid separator is as announcing No. 545281 patent case (call in the following text and quote case as proof), its main composition is characterized as: a kind of cryospray drying solid-liquid separator, include: the Raw material pail of adjustable low temperature, be provided with vaporific nozzle head, the hothouse of drying machine and confession oven dry, pumping raw material by the group Pu therebetween connects through delivery conduit, spray in mist attitude mode by vaporific nozzle head, it mainly is the contact-making surface that enlarges oven dry, again by cold-hot row exchanging device in the drying machine by compressor through the hot type device add hot-air and heat outputting and dry hot gas after a wind conveying pipe becomes the solid of steam and powdery with vaporific raw material stoving to the hothouse, powder falls down then collection in advance because of heavier; Both sides are set up a hollow clapboard respectively under wherein in the hothouse, also in Raw material pail common low temperature are arranged in the dividing plate, mainly are to allow powder is difficult for being adsorbed in the hothouse in the collection process; Right steam enters through another wind conveying pipe partly that cold-hot row exchanging device will condense into water with its steam cooling by a compressor by the cold air of this output through the cold type device in the drying machine, adding a screen pack in its wind conveying pipe went into to intercept a little powder, its water is received the water pond collection by one and is refiltered by a reverse osmosis equipment through delivery port again, through the continuous effect that circulates and reach the separation of solid, liquid attitude of the hot and cold gas of this process; And this is quoted its drying machine of case major defect on constituting as proof and is: (1) cold-hot row exchanging device adds hot-air and heat outputting and dry hot gas are exported through a wind conveying pipe by compressor through the hot type device.(2) steam partly enters through another wind conveying pipe that cold-hot row exchanging device will condense into water with its steam cooling by a compressor by the cold air of this output through the cold type device in the drying machine.
