Tan Lua Vang redefines the meaning of its craft piece

Feature of Rice Roller

Lua Vang brand

This autonomous brand is renowned by Tan Lua Vang, especially for its more than three decades of experience in the rice milling industry. Rollerpiece is applied in rice mill machinery as a scientific method for dehusking rice paddy grains. The key differentiator resides in the combination of market-driven product performance and innovative technology.
The refined revisions of Lua Vang facilitate the use of rice rollers. New equipment significantly enhances the accuracy of the final dimensions in terms of length, O.P., I.D., and LI, as well as dependability, flexibility, and durability.
Prioritizing the quality of rice-shaped products, Lua Vang has introduced differentiation products in colour, hardness of shore, and size to its collection in order to accommodate user behaviour.

Application of rubber roller in rice drilling machine in detail

Structure of Paddy Rice And How The Rice Is Created
Structure of Paddy Rice And How The Rice Is Created


The configuration of the roller itself contains features that aid in separating the husks from the rice grains in order to produce white rice, thereby bolstering the rice milling industry. Indeed, simultaneously attaching two crafts roller-pieces with the same diameter. Rice flows down a chute and is entrained between two rubber-coated rubber. One roller will run at various speeds over time (slow roller), other roller remains stationary / fixed in status (fast roller) – rotational direction: CW-CCW. In contrast, the second roller is also changeable in accordance with the intended clearance based on “the operating parameters (load, gap roller speeds, and speed differential of suck huskers are largely set experimentally on examining the processed product”. It adheres to the precise operation of equipment. Attached to the machine’s base is an aspirator for separating the husks from the white rice.

Info rice drilling machine works

Husk paddy (Peeling) by two rubber rollers that rotate in opposite directions and do not have the same rate of turn. The two inclined plane-placed rubber rolls and an adjustable chute together with a shaking section make a material current with a one-grain layer thickness to go straight into the slit of two rubber rolls.

Features of Rice Roller

The rice rubber roller should be constructed of a durable material that can be selected for its oil and resistance properties. This gives a better yield and output of the material processed.

Feature of Rice Roller

A compounded rubber material provides

  1. Strength,
  2. Resiliency,
  3. Temperature Resistance,
  4. Durability, Flexibility
  5. And The Capacity to Withstand all the Mechanical Stress And Forces.
  • A HIGH bonding ability is required as the rubber should be separated from the steel shell.
  • The rubber roller should be made heat-resistant so that it can handle high heat. It should also have low thermos plasticity and ensure the most durability.
  • The rice rubber roller should be made of a shelling capacity so that it can pass one cycle without breaking the rice grain.
  • The hardness of the rice rubber roller ( Shore 88 to 95) should depend on the quality of the rice and should get maximum shelling efficiency. It should not lead to the forming of rice grains that are of smaller size.
