STZL Series Retentioner

It is mainly used for long-term quality guarantee and ripening of fish and livestock and poultry materials. At the same time, it can kill viruses and bacteria through high-temperature steam.

Key benefits

Efficient virus killing

Through the combination of conditioner + retentioner, the conditioning temperature is > 85 ℃, and the conditioning time can exceed 120s.

Sanitary

Jacketed integrated large access door, easy to open, convenient for maintenance and cleaning, and there is no dead corner. The door body is filled with insulation cotton for all-round insulation.

Convenient operation

The self-locking hinge structure of the access door automatically locks when the door is opened, which is convenient for operators to repair and clean materials.

Highlight Features

Good performance

Hollow out spiral rotor can effectively improve the fullness; The end equalizing device improves the uniformity of discharging and the current of the granulator changes smoothly; Low residue and hygienic; All stainless steel in contact with materials. The whole length of the body is jacketed for thermal insulation, which has good thermal insulation effect and higher gelatinization degree.

Advanced design

Variable frequency speed regulation, effectively improve the fullness, up to 40%-70%.

Modular design and free assembly.

Safe and reliable

The shaft end adopts adjustable packing mechanism, which has reliable sealing, long service life and no leakage; Convenient maintenance. Humanized design, each access door has a safety switch, and the motor cannot be started when the door is opened to ensure the safety of operators. Torsion arm reducer, long service life; The reducer is directly connected with high transmission efficiency.
