DEHUSKING RUBBER ROLLER FOR RICE MILL (10”/12”) (PRODUCTION RATE – 20 PAIRS PER DAY)

[EIRI/EDPR/4554] J.C.: 2771US$

INTRODUCTION

Rubber Roller is a rubber or an elastic material covering the core of metal or other material. Rice Dehusking Rubber Roll are precisely made and fitted with the fresh CI drums and aluminum drums.  These rolls are specifically used for dehusking of raw rice. Due to the use of these rolls, raw rice gets perfectly polished and whiten.

Rice (Oryza sativa L.) has been the staple food for more than half of the humanity in the world or two-third of the World’s population. Rice is the seed or kernel of paddy, which is covered by two different layers, namely- bran (inner layer) and husk (outer layer). Literally, paddy becomes rice only when the two layers are removed properly through different milling processes. In the first step, brown rice is extracted by removing hull/husk from the paddy, which contains bran layer still intact around the kernel. In the second step, the bran layer is removed by polishing machine that rubs the grains together under pressure, and the output is the polished white kernel or fine rice, which is ready for cooking. The former process is known as hulling and the latter is known as milling of paddy. But, in short, it is the conversion ratio from paddy to rice, or one can term it as hulling and milling ratio. Therefore, the two terms-1) hulling and milling ratio; 2) conversion ratio, will be used interchangeably throughout this paper.

In term of production, India has become the second largest producer of rice in the world (21 per cent of global rice production), next to China. 

Generally, rice kernels are often susceptible to breakage due to inefficient milling processes. Therefore, more efficient milling processes are highly recommended for better recovery ratio and quality rice kernel production. It is also identified as one of the most important remedies for preventing post-harvest loss and an issue that is widely recognized around the world.

The processing of rice involves a number of discrete operations from husking to whitening and polishing. The efficiency of each affects the quality and hence market value of the finished product. Further, each of the operations is energy intensive and because the through put is so great can cause extreme wear to many of the machine parts. There is therefore great interest in maximizing the efficiency, increasing machine reliability, and minimizing damage to grains during such operations. 

Rice as an agricultural material must have its husk removed (husked) in order to be useable as a commercial product. Two types of machines are commonly adopted in husking; impeller type and rubber roll type machines. In impeller type husking machines, the rice is scattered radially and husked by the impact of collision with an external surround. The impeller type huskers are not inherently inferior to rubber roll huskers, but continuing advancements of rubber roll type have led to their diminished use. This study focuses solely on the latter process.
