METHOD FOR THE PREPARATION OF AIR-ENTRAPPED PRODUCTS AND DEVICE THEREFOR

摘要

Constituents are introduced into a receptacle (B) through which there slides a piston (A) connected at its lower part to at least one element (D) provided with a multi-channelled passage (C). By reciprocating the piston (A) in the receptacle (B), air or inert gas is entrapped into the liquid or liquid- solid mixture. Spring (E) assists in the reciprocation. The passage (C) diameter is preferably in the range 0.2 mm to 10 mm. The piston (A) may be guided and sealed against the receptacle (B) by an O ring (Fig. 2).
