Horizontal GMP Peeler Centrifuges SS316L For Food Industry

Product Description

GKF Horizontal GMP Peeler SS316L Automatic Batch Operation Centrifuges For Food Industry

With special structural design and system configuration, GKF pharma peeler centrifuge can be used to obtain pharmaceutical products or intermediate products that meet the GMP (FDA, COS, TGA) standards with reasonable consumption, without generating new impurities and pollutants during the operation.

GKF centrifuge series are new types of products integrated with multiple patents.

Scope of application: particle diameter: 0.05mm~1mm

Solid content: 10%~50%

Cake density: 1~1.5

Characterized by automatic control, batch processing, continuous working, short circulating period, large handling capacity, low moisture and good washing effect, the product is applicable to the solid-liquid separation of toxic, hazardous, inflammable and explosive media of low viscosity and with high requirements for sanitation. It has been widely applied in the pharmaceutical production, food production and other fields.

Operation process

Feeding
The material enters the rotating basket through the feeding pipe, and the cake layer controller controls n times of pulse feeding to fill the basket in limited manner. Usually, the material cake can reach 75-80% of the basket lip. Feeding is completed once the solid cake reaches the pre-set thickness.

Filtration Skimming-Filtration
The mother liquid penetrates through the filtration medium across the inner wall of the basket to complete the primary filtration, which begins as the material enters and ends as the liquid just immerses the inner surface of the solid cake. For the mother liquid containing colloid protein, the mother liquid containing the colloid protein will be removed by means of the skimming device in the course of filtration.

Washing
The solid cake is usually washed after the primary filtration. Add the washing liquid through the feeding pipe or washing pipe, and level of the washing liquid is monitored in the material level detector. Washing is completed once the pre-set washing load is achieved and the solid cake is immersed into the liquid.

Dry spinning
The basket accelerates to the high speed for drying the solid cake, and filtration is completed after the moisture content of the solid cake reaches the required value or the solid cake takes the pre-set drying duration.

Discharging
The solid cake is removed by the scraping device at high speed or that is decelerating, and the removed cake is discharged through the discharge mechanism. The solid phase can be discharged in two modes: discharging chute and scroll conveyor.

Regeneration of filter cloth
Residual solid cake can be found on the inner wall of the basket after the scraper discharges the material, the filtration basket can loosen the solid cake through the high-pressure gas on the back of the basket, and then remove the solid cake by means of the scraper device. In the siphon basket, the back washing liquid can be added into the basket from the high-level-mounted back washing tank through the suction chamber, and then reversely penetrates the residual solid cake so as to make the solid cake suspended and restore its permeability.

Main Features

• Gas back-blowing device: assist the peeler to discharge materials and remove the residual cakes effectively.

• High-quality stainless steel or alloy is adopted for the part contacting materials, and surfaces are polished, meeting the requirements for corrosion protection and cleanliness

• Online cleaning system: Multiple spraying balls and directional nozzles are arranged on the inner surface, basket bottom, discharging bucket, door and other parts of the centrifuge to realize comprehensive flushing of the equipment online.

• Online SIP disinfection, CIP cleaning and soaking & cleaning are available to effectively avoid cross contamination of materials and meet the GMP standards and high requirements for sanitation.

• Variable-frequency control, energy consumption or energy feedback braking, speeds in different processes set as needed, stepless speed regulation are designed to reduce power consumption significantly.

• Automatic electric-hydraulic control is adopted for the actuating components, and feeding, filtration, washing, dehydration, discharging, residual cake removing, online cleaning and other processes are monitored in the whole process.

• System of multiple safety protection devices: devices for speed monitoring, overvibration protection, door opening protection, motor overtemperature and overload protection, electric-hydraulic interlocking protection for door locking, peeler position limitation, spindle temperature rise protection, lubrication interruption protection, etc. are configured to ensure safe operation of the centrifuge.

• Dual-sealing structure is designed for the spindle to effectively prevent oil leak and contamination.

• Diaphragm-type structure is designed. The power area and production area are flexibly connected through the base panel and wall, which are completely separated, so as to effectively prevent contamination in the production area.

• An automatic nitrogen monitoring system is configured to ensure the centrifuge always works under positive pressure of the inert gases, and an online oxygen content detection system is configured to meet the requirements for explosion protection.
