AUTOMISED CONTINUIUS TYPE SANDLESS ROASTER

Abstract

This Invention 'AUTOMISED CONTINUOUS-TYPE SANDLESS ROASTER' is aimed to provide an atomized, continuous type roaster, without using the intermediate mammal, which is normally sand, making tits process all more easier and hygienic. Further, this process also minimizes the dependency on man-power or skilled labour, 'which is a scarcity these doss. His unit basically surface of the rotating drum, which otherwise may result in over-roasting of grains. Further, this direct hen method, yields crisper grains.

Roasting of grains or granules is done by manual means, like Pan-Roasting method etc., which mainly depends on manpower and is not continuous and consequently time-consuming. Roasting of grains has to be handled by skilled-Labour, failing which the grains may get over-roasted and may result in a lot of wastage. In the Conventional Method of roasting grains/granules, the grains used to be roasted in a pan, heat being imparted from a burner/stove installed beneath the pan. Normally, it is to be done in open space, totally exposed to air. Further, conventional pan-roasting method occupies a lot of space, is tedious and is totally exposed, wherein there is scope for foreign particles to creep-in and result in an unhygienic process. Moreover, the intermediate material used in roasting is generally sand, has to be ensured is cam and does not carry any foreign material, which may otherwise spoil the whole system. The aim of this Invention is to provide an automised, continuous type roaster, which does not require an intermediate material i.e., SMd, thereby reducing the chances of any foreign body creeping-in and at the same time is more fuel-efficient now, as the intermediate material has been eliminated and because of which it is the direct heating of the grains or granules and as such making the entire process all the more simpler my easier. This newly invented Automised, Continuous, Direct Roaster can roast all types of particles without the requirement of an intermediate material for roasting i.e., said . Though no intermediate material is used, uniform heating of grains/granules is ensured. Further, there is no over-roasting of the grains also. As the entire system is totally automised. there is no absolute necessity of any skilled-labour and could be handled by anybody easily. Elimination of sand and non-exposure of the process to the atmosphere by virtue of the roasting drum makes the total operation totally hygienic. This newly invented 1AUTOMISED CONTINUOUS-TYPE SANDLESS ROASTER', basically consists of a Rotating Drum (1) (with reference to the accompanying Drawing) carrying a spiral arrangement (2) within it, there are a number of striker strips (3) in between the sup-al sheets, within the inner surface of the drum, which are parallel to the axle of the drum. Axle of the drum is mounted on two bearings (4) on either ends, duly supported on Column (5). The Rotating Drum derives power for its rotation from a Motor (7) and Pulley (6) 1ranged to meet the required torque and the speed (rpm). There is provision for manual handling also, in the event of power failure. As the drum rotates, the spiral arrangement within it makes the fed grains to travel from the inlet end to the outlet end. Outer surface of the rotating drum is heated by external heating. As the spiral arrangement is at a constant pitch throughout the drum length and the drum rotating at a constant speed (rpm), the travel of grains is at uniform speed from the inlet to outlet. The striker strips in between the spiral sheets and in the inner surface of the drum make the grains to mix within. As the grains get stirred by the strikers a number of times, uniform heating is achieved on the outer surface of each grain and also ensure that the grains do not get over-roasted as the striker strips also act as a barrier to the grains for continuous contact with the inner hot surface of the rotating drum. Due to the rapid mixing process toeing place with the rotating drum, heat is transmitted uniformly and distributed amongst other grains. The provision of striker-strips has thus taken the place of the intermediate material, whose purpose is more than adequately provided by the striker strips, thereby facilitating easy handling, making the process more hygienic and saving a lot of fuel because of the direct heating. Another added advantage of this direct Sidles roasting is that the moisture content of the grains is drastically reduced and as such the grains are more crisper, as compared to when roasting with intermediate material md further, one step is totally eliminated i.e., separation of sand and grains after each batch, which saves a lot of time. Principle being the essence of the Invention, the shape and size of the rotating drum, spiral arrangement and strikers, speed of the drum and method of drive etc., could be varied to suit the requirement. We Claim, 1. An AUTOMISED CONTINUOUS-TYPE SANDLESS ROASTER', comprising of a Rotating Drum with a spiral arrangement within; with a plurality number of striker strips in between the spiral sheets, all arranged within the inner surface of the drum, in a manner parallel to the axle of the drum wherein the axle of the drum is mounted on two bearings on either ends, duly supported on columns; the rotating drum deriving power for its rotary motion through a motor-pulley arrangement. 2. An 'AUTOMISED CONTINUOUS-TYPE SANDLESS ROASTER', as claimed in Claim (1), wherein the spiral arrangement within the rotating drum has a constant pitch throughout the length of the drum and the rotating drum rotates at a constant speed.
