The object of the invention is to overcome the deficiencies in the prior art part, provide and process ultrafiltration tank bottoms Special vacuum rotary drum filter and ultrafiltration tank bottoms processing method, this vacuum-type drum filter has increased ultrasonic generator and enzymolysis liquid entrance on the basis of existing filter in lautertuns, open ultrasonic after, the separating rate that can increase fruit juice and active carbon improves tank bottoms disposal ability, increase the chocking-up degree that can reduce cloth soil after enzymolysis liquid, the fruit juice increasing after treatment effeciency reclaims can continue to use after the enzyme that goes out simultaneously.
The object of the invention is to be achieved through the following technical solutions:
A kind of processing ultrafiltration tank bottoms Special vacuum rotary drum filter, comprise rotary drum driving device, lautertuns, rotary drum, dispensing head, agitating device, it is characterized in that: inner bottom part one sidewall at lautertuns is installed a supersonic generator, at lautertuns one sidewall, be shaped with enzymolysis liquid entrance, enzymolysis liquid entrance connects enzymolysis liquid front pump.
And described enzymolysis liquid front pump adopts motor to drive.
Vacuum-type drum filter is processed a ultrafiltration tank bottoms processing method, and step is as follows:
(1) drum surface cloth is native: the rotary drum of vacuum-type drum filter is carried out to rotary drum and carry out cloth soil, cloth soil thickness 4cm, with native: perlite, thick soil, fine earth; Three kinds of soil is cycling coating in order repeatedly from inside to outside;
(2) after filling substrate being diluted with water, be placed in lautertuns, start agitating device, tank bottoms comprises the insoluble solids such as active carbon and fruit juice; Stir and open supersonic generator simultaneously, process 20-30 minute;
(3) pass into enzymolysis liquid, described enzymolysis liquid consists of: amylase, pectase, protease, cellulase, and its addition can regulate according to the content of insoluble solid in tank bottoms, and add and continue to stir 0.5-1 hour after enzymolysis liquid,
(4) led to after enzymolysis liquid and started drum drive unit, driven rotary drum to be rotated filtration, after filtering, active carbon is filtered to drum surface, when thickness to a certain extent after, with device for discharging, removed;
(5) the fruit juice that filters acquisition clings to and kills, and sterilization joins unified ultrafiltration and the subsequent step of carrying out in original fruit juice after the enzyme that goes out;
(6) the cloth of active carbon and drum surface soil one is logical removes as solid refuse.
And, tank bottoms disposal ability: 206kg/h.m after described cloth soil
2, fruit juice flux: 157.5kg/h.m after cloth soil
2.
And, during described cloth, after 2.5-3cm, be coated with fine earth, final coating layer thickness 4cm.
And, in described enzymolysis liquid, the addition of various enzymes is: amylase: diastatic addition is the 0.001-0.01% of tank bottoms weight, pectase: the addition of pectase is the 0.002-0.05% of tank bottoms weight, protease: the addition of protease is the 0.002-0.02% of tank bottoms weight; The addition of cellulase is the 0.002-0.05% of tank bottoms weight.
Advantage of the present invention and good effect are as follows:
