Description
Technical field
This utility model belongs to food vacuum freeze-dried food equipment, more particularly to a kind of freeze dryer of defrosting it is negative
Pressure steam generator.
Background technology
Along with development, the progress in epoch and the raising of living standards of the people of society, food industry is just towards nutrition, strong
Health, function, convenient, easy to maintain direction stride forward.In recent years, vacuum lyophilization food apparatus（Hereinafter referred to as FDF equipment）Work
Skill is widely used, and is in the ascendant.
FDF technologies are that first food containing water material is frozen into below its eutectic temperature so as in moisture become ice, so
Afterwards at appropriate temperature and vacuum, Shi Bingsheng Huawei steam is escaped from material, recycles cold-trap that steam is sublimated into ice,
So as to obtain the process of dried foods.After each lyophilizing of FDF equipment is completed, substantial amounts of ice can be trapped on cold-trap, next
Need thoroughly to remove ice before task.Overwhelming majority freeze dryer is to use water defrosting at present, occasionally has Boiler Steam to defrost, so not
Substantial amounts of water source, the energy are only wasted, substantial amounts of waste gas discharge is also produced, is caused environmental pollution.
The content of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, there is provided a kind of utilization vacuum freeze itself it is true
Empty, heating system, completes the negative pressure steam generator of cold-trap deicing and the freeze dryer of condensing hot air furnace.
This utility model solves the technical scheme that adopted of technical problem：A kind of negative pressure steam generator of freeze dryer,
Including cylinder, end socket is welded with the two ends of cylinder, it is characterised in that be fixed with tube sheet at the intracavity two ends of cylinder, in tube sheet
It is provided with the hole of bottom.
The beneficial effects of the utility model are：The utility model saves water resource, the energy, and through type tube bank makes water
Flow resistance is little, and logarithmic temperature difference is big, and heat exchange efficiency is high, pollution-free, is conducive to environmental conservation.
Description of the drawings
Below in conjunction with accompanying drawing, illustrated with embodiment.
Fig. 1 is the front view of the negative pressure steam generator of freeze dryer；
In figure：1- cylinders；2- steam (vapor) outlets；3- tube sheets；4- end sockets；5- hot water outlets；6- heating tubes；7- water supplement ports；8-
Bearing；9- hot water inlets；10- ring flanges.
Specific embodiment
Embodiment, referring to the drawings, a kind of negative pressure steam generator of freeze dryer, including cylinder 1, weld at the two ends of cylinder 1
Be connected to end socket 4, it is characterised in that tube sheet 3 is fixed with the intracavity two ends of cylinder 1, be provided with uniform in the hole of the bottom of tube sheet 3
Distribution parallel equidistant ground is equipped with five heating tubes 6.
A steam (vapor) outlet 2 is filled in the middle of the top of cylinder 1, below in the middle of be equipped with water supplement port 7, the center of end socket 4 on right side
A hot water outlet 5 is welded with, 5 termination of hot water outlet is fixed with ring flange 10, in end socket 4 lower weld, one hot water in left side
A ring flange 10 is welded in import 9, the termination of hot water inlet 9.Cylinder 1 is mounted on bearing 8, and 1 intracavity of cylinder is equipped with water.
The all of parts of the utility model adopt the connection of stainless steel material, each part to be welded with rustless steel argon arc welding
Connect and form.
The course of work is：Open steam (vapor) outlet 2 valve, the pressure in cylinder 1 at once with the vacuum storehouse pressure balance taken out in advance,
Hot water is entered by hot water inlet 9 simultaneously, is flowed out to hot water outlet 5 by heating tube 6, when hot water flows in heating tube 6, to cylinder
Water heating in body 1, water will be evaporated at the corresponding temperature of vacuum pressure at this moment, and reaches vacuum storehouse by steam (vapor) outlet 2,
The ice-out that the latent heat of vaporization makes on cold-trap is discharged, this process is constantly carried out, and just completes cold-trap ice detachment.
