Description
Technical field
The present invention relates to a kind of brown fruit yeast killer more particularly to a kind of control systems of brown fruit yeast killer, belong to industrial control
Technical field processed.
Background technology
After fresh palm fruit picks, it need to carry out killing ferment processing, otherwise the lipolytic enzyme meeting in its fruit in 24 hours
Grease therein is decomposed rapidly, becomes glycerine and aliphatic acid, its economic value is made drastically to decline.
Traditional palm fresh fruit kills ferment generally use tunnel type（It is horizontal）Bundle sterilizing tank, the loaded ramp of palm fresh fruit string are packed into
In one row fruit cage train, fruit cage train is drawn through capstan winch, commutation stake and conveyer table, and tunnel type bundle sterilizing tank is moved into along track.
One bundle sterilizing tank can at most fill eight fruit cage trains, and when killing ferment, bundle sterilizing tank both ends end socket gate is latched, and 3-3.5Bar is passed through in tank
Water vapour, after free gas is discharged, pressurize completes high temperature and pressure for 1 hour and kills ferment, then empties water vapour, hauls out fruit cage train,
It is had bad luck to cardump car by capstan winch, track bridge, conveyer table and track, fruit cage train is overturn 180 ° by cardump vehicle, pours out fruit cage row
Car kills the ripe fruit string of palm of ferment completion, and subsequent process is delivered to through drag conveyor.Traditional kills the investment of ferment system equipment greatly,
Low production efficiency, occupied ground are big；High energy consumption, bundle sterilizing tank capacity utilization is low, and safety is poor, and the labor intensity of operative employee is big.
Novel pressure type palm fibre fruit yeast killer includes horizontal circular cylinder body, the head end top of cylinder be equipped with feed inlet and into
