Abstract
A dispensing and weighing system for multiple ingredients, including a plurality of individual ingredient batch weighers. Each batch weigher includes apparatus to store and dispense a particulate material to a scale from which the weighed portion of the material is intended to be delivered to a pneumatic ingredients delivery conduit. The pneumatic conduit discharges into a weighing hopper, where the weight of all of the batches delivered to the hopper is determined. A method for dispensing individual, weighed batches of particulate material, and for determining the total weight of the material actually delivered to a receiver.
Claims9
Apparatus for dispensing pre-selected quantities of multiple particulate material ingredients comprising:
- (a) plural storage hopper means, one for each of a plurality of ingredients,
- (b) plural ingredient weigh scales, one for each of said ingredients,
- (c) means for discharging the ingredient from each storage hopper means to a respective weigh scale,
- (d) a pneumatic ingredients delivery conduit,
- (e) means for delivering ingredient from each said weigh scale to said delivery conduit, and
- (f) means for receiving and for weighing the total quantity of material delivered by said delivery conduit,
- (g) whereby the total quantity of material delivered is compared with the sum of the weights indicated by said ingredient weigh scales.
A particulate materials dispensing and weighing system comprising:
- a plurality of batch weighers, each batch weigher comprising a hopper for material, a scale, means for delivering material from the hopper to the scale, and means for discharging material from the scale,
- a pneumatic ingredients delivery conduit,
- conduit means connecting each said discharge means with said delivery conduit,
- a receiving hopper having an inlet and a valved outlet,
- said conduit means having a delivery end connected to the inlet of said receiving hopper, and
- means for determining the weight of material delivered to said receiving hopper,
- whereby the weight of the materials delivered to the receiving hopper is compared with the sum of the weights of the materials delivered from the batch weighers.
A method of dispensing and combining pre-selected weights of particulate material ingredients comprising:
- individually storing a plurality of ingredients,
- weighing a pre-selected portion of at least a plurality of said ingredient,
- providing a pneumatic delivery conduit for delivering particulate material,
- providing a branch delivery conduit for transferring individual weighed material portions to the pneumatic delivery conduit,
- and collecting the material delivered by the delivery conduit and weighing the collected material to provide a comparison of the total weight of the material delivered and collected to the sum of the weight of the weighed pre-selected portions.
