1, round bottom or flat bottom rotisserie machine: this rotisserie machine manufacturing cost is low, but consume more fuel, soybean milk is easy to caramelize, low output rate, do not recommend the use of, is now basically eliminated. 2, water bath rotisserie machine: this rotisserie machine soybean milk is not caramelized, rotisserie is not easy to caramelize, equipment structure is simple, less investment, but the skin is slow, energy saving effect is not ideal, burning fire, only the upper part of the fire is used to bake the bottom of the pot, the labor intensity is large, this kind of rotisserie pot, although the price is very cheap, but it is difficult to control the temperature of the uniformity, and pot surface is easy to bulge in the local area.

3, with domestic hot water roti machine: this roti machine is not easy to scorch, roti quality is relatively good, but can only be used in a shorter pot, low yield, slow crust, roti machine surface may bulge.

4, aluminum roti machine: this roti machine already has the prototype of modern advanced roti machine, soybean milk is not scorched, high yield, but there may be leakage of water leakage of slurry, aluminum pot is easy to be corroded, not durable.

5, coupled with steam generator roti machine: this more advanced roti machine, steam generator can well absorb the heat of the fuel, and at the same time to ensure a very long roti machine pot end temperature is consistent, roti good quality, high yield, low labor intensity, but due to the steam generator can not be separated from the pot surface, the maintenance of the more difficult.

6, Split type with steam generator: this is an advanced machine for making roti bamboo, improved on the basis of the previous generation, it can realize the separation of the steam generator and the pot surface, while retaining all the advantages of the previous generation of roti machine, to solve the maintenance problem, convenient for future maintenance, it is the more ideal roti machine at present.
