Pre-frothing device FP-03 for polyfoam producing.
Pre-frothing device is a cylindrical capacity, inside having an activator of stainless steel for granules scrambling. Rotation of activator is provided by engine-reductor. Pre-frothing device is supplied with device for manual loading of raw material, unloading is made with the help of pneumatic remodeling system ventilator. As warmer water steam is used which is given through perforated bottom sheets of stainless steel.
Appointment: Pre-frothing device is appointed to primary and secondary frothing of granules by warm processing method. Secondary frothing is possible with the help of additional device only.
Principe of work: Mode of work is periodical. Capacity is hermetic that allows to save steam and inner redundancy atmosphere. That raises speed of frothing in comparison with pre-frothing device of unceasing action.
Pre-frothing device with double winterized walls model FP-04. Winterizing is used for steam saving and quality of granules upgrade..
Pre-frothing device with inner cavity of stainless steel model FP-05. Application of stainless steel increases corrosion stability of inner cavity.
Pre-frothing device with double winterized walls and inner cavity of stainless steel model FP-06.Joining of these features saves steam, upgrades quality of granules, increases stability of product.
Secondary frothing device is applied as additive to any model, is used to get easier granules.
Automatic block of pre-frothing device. Provides automation in the process of raw material dosage from accumulating bunker, regulating the process of steaming, unloading of granules to hold-distribution bunker.
Drying device with warm air pressure provides speed-up process of drying and stabilization. Is provided with ventilator, transporter for dry granules moving.
