Pump system for food machine

摘要

Dual foods pump arrangement that includes a pump manifold, two food pumps, and a rotary valve element removably located within the manifold. The rotary valve element is operated to selectively direct the flow of food product from the two food pumps in alternating fashion through a single manifold outlet. The food pumps are driven by servo actuated cylinders. A tool is provided for lifting the valve element from the manifold that includes a pivotal removal bar that can be attached to a top of the valve element.

1. A dual food pump arrangement comprising:
a pump manifold having a first manifold inlet, a second manifold inlet, and a manifold outlet, said manifold outlet being a single nozzle; a first food pump within a first pump cavity and a second food pump within a second pump cavity, the first pump cavity having a first outlet open into the first manifold inlet and the second pump cavity having a second outlet open into the second manifold inlet; and a rotary valve element disposed within the pump manifold, the rotary valve element rotatable about a substantially vertical axis within the pump manifold to selectively direct the flow of food product through either the first manifold inlet or the second manifold inlet to the manifold outlet; wherein the rotary valve element has a support rod which extends between the bottom of the rotary valve element to the top of the rotary valve element, wherein the support rod is disposed off center from the substantially vertical axis.
