What is Unifloc Machine? How it Works?
Unifloc Machine
In a Industries opening of the cotton bales having weight around 160kg is done with the help of unifloc machine. This unifloc machine consist of a beater which has an excellent opening system after opening at this machine the tufts of cotton are pushed into pipes and are made available for another processes with the help of blower.
MACHINE SPECIFICATION:-
No. of machine = 2
Make = RIETER
Model = A – 1/2
Transverse speed = 9.5 mpm
Production = 900 – 1000kg/hr.
DUST GAUGE:-
The open tufts of cotton are feed to the dust gauge after opening through unifloc machine with the help of suction. In this section the large dust and small particle are removed from the tufts of cotton.
METAL DETECTOR:-
At this stage any foreign like metals are detected and get separated with the help of the suction from the tufts of cotton.
Objective:-
Cotton fibres arrives in the mill in hard presses bales. So the objective of the blow room is to properly open this hard presses bale of cotton into small tufts. Opening of fibres in the blow room involves not only breaking the stock into small tufts but also to removes the impurities like dust, seed, metal pieces, pouches, stones etc. Opening of fibres in the blow room is essential to properly carry out the subsequent process of carding, drafting, roving and spinning.

HUMIDIFICATION SYSTEM:
The humidification system plant mainly comprises of the rotary filter, dampers and humidifier.
The micro dust is being transferred to the rotary filter (consisting of a large filtering cylinder) where the micro-dust is retained and dust free air is sucked in with the help of travelling nozzles. The purified air obtained is now transported via a suction fan to the humidifier and dampers. The function of damper is to control the flow of air to the department and also to sense the required relative humidity of the air. In case of low humidity the air is transported to the humidifier where the dry air gets humid and is transferred to the department. Almost all the department in Auto Industry Ltd. employ the system of humidification and sucked in waste is being re-circulated along with proper filtration.
