Rice Polisher Rubber Brakes are rubber profiles manufactured with a blend of carefully selected polymers and ingredients to deliver the optimum performance at the best price over the years . Primarily they are used for polishing grains like rice to have a long lasting lustrous appearance. Rice Polisher Sizes The widest range of sizes are available with us covering all possible machine types operating in the market. Different grades are available to suit the processing types and paddy types in different areas. The product is designed to deliver highest output with lowest broken rate of grains and optimise the cost to output ratio.    

An economical substitute for conventional steel buckets on account of economical pricing, longer life, low power consumption and fast smooth and clean discharge with a very low percentage of broken grains/granules. Manufactured from virgin food grade, heat and corrosion resistant polymers in sizes ranging from 4” to 14”. Application Area & Sizes The buckets are designed for extra heavy duty performance even in heated environments Only 100% virgin food grade raw materials are used The buckets are Non Toxic and safe for handling food grains.

Paddy has to be dehusked and polished to convert it into the marketable form of white rice. In the past, dehusking of the paddy was done manually by pounding the paddy in a receptacle with a wooden stump. This was later replaced by mechanical dehusking with the use of rubber rollers, which gave a greater dehusking efficiency and less grain breakage. When Malaysia started her factories in the 1970’s, the rollers produced were based on silica-filled styrene-butadiene rubber (SBR) compounds because of their longer service life and better thermal stability compared to natural rubber (NR) rollers. However, lately many alternative materials such as acrylonitrile rubber especially the carboxylated grades, polychloroprene rubbers, EPDM, etc. were being used to give even longer service life than the SBR rollers. Paddy Dehusking Rubber Roll Sizes In a modern rice miller, a pair of rubber-lined rollers are mounted in an enclosed chamber and driven at a friction ratio. A typical unit using 254 mm nominal width x 254 mm outer diameter rollers run at 1.28 : 1 friction ratio with the faster roller at 900 revolutions per minute. The nip of the rollers is manually adjusted during dehusking to compensate for the gradual abrasion of the rubber surface and its thermal softening. The paddy in passing through the rollers nip is subjected to both compressive and shearing forces. When these forces are correctly predetermined for a particular grade of paddy (by rubber hardness, resilience, rollers nip, speed and friction ratio) the paddy will remain substantially intact after going through, while the husk is broken off. In practice, the dehusking efficiency can be as high as 90% per pass.    

Vacuum Hoses are pure polymer hoses designed with some special characteristics like self clamping and high temperature withstanding capacity. Customized sizes are available as per the customer requirements and are primarily used as connectors with leak proof characteristics. Application Area The primary area of application are vacuum lines and vacuum pumps. Also used widelyin area with more than normal ambient temperatures to avoid accelerated aging and crack formation.
