Automatic Weighing Machines

Basic Overview The entire range of Easiweigh weighing machines have the same basic mode of operation and whilst the format, style, size and specification may differ to suit different products, weights and speed requirements basic principles are valid throughout.
	The easiest way to understand what the machines do is to compare them with the method of weighing product, by hand, using a set of static scales. Taking a simple example of weighing an ingredient necessary for baking a cake what are the basic requirements?
	Some means of weighing - in this case a set of simple kitchen scales will suffice.(We could call this the "weighing system")
	Some means of getting the flour from its large packet into the cake mixing bowl - for this purpose a large spoon or scoop will do. (We call this the "product feed")
	Someone to carry out the weighing (Lets call this the "control system")
	The product you wish to put in the cake - (Lets assume that this is flour)
1. First you make sure that with no product on the scales (weighpan) the displayed weight is equal to zero - if not adjust it or make a note of the reading and make an allowance for the required weight (target weight). 2.You then open the large bag of flour (bulk product) 3.Taking the spoon or scoop you transfer the product from the bulk to the scale pan as quickly as possible (bulk feed) keeping an eye on the scale display. 4.When the displayed weight nears the target you then slowly trickle flour from the spoon (fine feed) until the desired weight is displayed. 5.The scale pan is then removed and the contents tipped into the mixing bowl (discharge). To all intents and purposes this is precisely what the weighing machine does. Product is placed into a holding hopper and is then fed automatically, at a fast speed, into a pan that is attached to a weighing mechanism until the target weight is almost reached at which point the feed rate slows to a trickle. On achieving the required weight feed stops altogether and, after checking that the weight is correct, the weighed product is released into a waiting container.
