TYPES OF DISHWASHER 

The Dish Washing is carried out  in two methods mainly :- Manual method and Machine wash method. The selection of dish washing machine depends upon available infrastructure ,space, water supply, waste water discharge system and operational budget of the firm.

Manual Dish Washing procedure 

The Manual Washing Method is carried out in sinks and can be performed in two three, four, and five sink washing method. It varies according to sink.

The various sink washing method are given below -

1. Two sink Method :


The first sink contains a hot water and soap solution, and the second sink contains tepid warm water. The stacked and grouped dirties come in their groups to the first sink and here they are manually scrubbed with the hot water detergent solution after which they are passed to the second sink where they are rinsed in tepid water. After which they are sterilized by hot steam and then wiped/dried and sent to the plate room and silver room accordingly.
Note:- The detergent needs to be changed very frequently

2.Three sink method :-

Here, the first sink contains a hot water and soap solution, and the second sink contains tepid warm water and the third contains hot water. The stacked and grouped dirties come in their groups to the first sink and here they are manually scrubbed with the hot water detergent solution after which they are passed to the second sink where they are rinsed in tepid water. After which they are again dipped in hot water to remove any detergent sticking on the surface. Thereafter they are sterilized in hot steam and then wiped/dried.
This system is practiced in a very busy outlet.

3. Five sink Method :-


Here, the soiled articles from two sides are first dipped in hot water solution, where they are scrubbed and ensured that the adherents are removed. Then the articles are passed to the second sink where the detergent is washed from the article and finally they are put in hot water to ensure the article is absolutely clean. Thereafter, the articles are passed through steam and are sterilized.
This is actually a replica of the first method of two sink washing system. Here two types of equipment’s can be washed simultaneously. If the manpower is adequate then this system is effective and as the final rinse is given in a common saves the consumption of water and since the same hot water can be used for washing two articles it also saves energy.

The timer is set to determine how long the articles are to be washed. Then by the conveyor system the articles are transferred from one chamber to another after which finally they come out sterilized and dried. It is found in large establishment.

3.Flight Conveyor

The wired baskets are fixed to the conveyor into which the articles are placed. The timer is set and upon switching on the machine the conveyor rolls the basket in, into the chambers where the soiled articles are washed rinsed, sterilized and dried automatically. Thereafter the basket comes out from which the washed articles are off loaded.
