Whipping apparatus

Claim 2

A static-type whipping apparatus as set forth in claim 1 wherein the impediments are made of a synthetic resin compatible with the material and gas, said impediments each having an irregular shape and together providing the multiplicity of interstices.

Claim 3

An apparatus as set forth in claim 3 wherein the synthetic resin impediments are surrounded by a tubular net of synthetic resin, thereby facilitating insertion and removal of the impediments.

Claim 4

In combination with a container for holding a whippable food material such as animal or vegetable fat cream, a whipping tube having inlet and outlet ends, means for feeding a gas into the whippable food material prior to the inlet of the whipping tube, and static whipping means in the whipping tube providing a multiplicity of interstices crosswise and lengthwise of the whipping tube to intermix the material and gas and provide a whipped food product; the improvement comprising: an intermittently operable pump operatively connected to the container and to the inlet of the whipping tube for pumping the whippable food material to the whipping tube; a check valve between the pump and the whipping tube for preventing backflow of the material and gas from the whipping tube when the pump is stopped; an outlet valve at the outlet of the whipping tube to control flow of whipped food product therefrom; control means for starting the pump simultaneously with opening the dispensing valve so that the whippable food material is pumped from the container and the material and gas is forced through the static whipping means, and the control means also including means for stopping the pump simultaneously with closing the dispensing valve so that the material and gas mixture is maintained in its relative position in the whipping tube between the dispensing valve and check valve.
