Accordingly, the consistency of the confectionery product is maintained when the pump is idle. The peristaltic pump also includes a proximity switch which prevents the pump from operating until all of its movable parts are properly secured.

Abstract: A collection vessel and method of collecting gaseous and liquid phase collectible materials utilizes introduction of the collectible material directly into a liquid cryogenic material to provide complete condensation and a liquid-filled trap for collected gases within the liquid cryogenic material. This trap effectively eliminates escape of collected gases even though evaporated cryogenic materials may be vented and the collection vessel operated at atmospheric pressure. The performance of the vessel is thus improved and no freezing of the collected gases occurs at the inlet due to the warming of the inlet structure by the material being collected. Therefore, the collection of gases may be done at high speed and with simplified equipment. Completeness of condensation is assured by the use of a baffle of a preferably collapsible construction for retaining gases within the liquid cryogenic material until condensation is complete.
