A method for controlling foam comprising providing a food composition comprising a foam control agent and a foodstuff, the foam control agent; and processing the food composition. A food composition comprising a foodstuff and a foam control agent.

Defoamer preparations contain a polyorganosiloxane having aryl groups bonded to silicon at a ring carbon, filler particles and/or silicone resin particles, and a polyoxyalkylene polyether containing oxypropylene moieties. In addition to being efficient and compatible, the defoamer compositions retain their efficiency, especially in liquid detergents, after storage.

Various embodiments relate to devices and methods for treating a mixture of expansion gas and filling product foam in a beverage filling plant, comprising the steps of introducing the mixture of expansion gas and filling product foam into a closed separation container and extracting the expansion gas out of the closed separation container via suction.

An arrangement for preparation of a distillation measurement of a liquid includes a heater and a traversing system. The heater supports a perforated plate selected from a group of standardized perforated plates which further supports a container containing the liquid. The heater is enabled and controlled during the performance of a standardized test for determining evaporation properties of the liquid. The traversing system is adapted to traverse the heater and to interrupt a further traversing of the heater, if a pressure force of the perforated plate put onto the heater against the container reaches a threshold value.

A method of managing foam in a gas processing system includes flowing a gas processing solution through a processing line and flowing an antifoaming agent through a treatment line into a mixed fluid line to form a fluid mixture, determining a foam level of the fluid mixture at a foam controller disposed along the mixed fluid line, automatically controlling a valve disposed along the treatment line to control a flow rate at which the antifoaming agent is flowed into the mixed fluid line to achieve a target dose of the antifoaming agent to be mixed with the gas processing solution in the mixed fluid line based on the foam level determined at the foam controller, and flowing the fluid mixture containing the target dose of the antifoaming agent into a system component to prevent an amount of the foam in the gas processing system from exceeding a threshold amount.

A non-silicon defoaming agent, includes an acrylate polymer, an organic solvent carrier, hydrophobic particles and defoaming auxiliaries; and the acrylate polymer is prepared from following raw material components: monomer-1, monomer-2, unsaturated terminated polyether, alkene, diluent and initiator. The present invention further includes a preparing method for the non-silicon defoaming agent and the application of the non-silicon defoaming agent to the defoaming and foam inhibiting in systems rich in anionic surfactants. The defoaming agent takes the acrylate polymer as the main active substance and has excellent defoaming and foam inhibiting performance. By dropwise adding monomers, the defoaming performance of the acrylate polymer is improved, by using unsaturated terminated polyether to modify, the hydrophilia of the acrylate polymer is improved, the instant defoaming capacity is further improved, and by the alkene with the carbon atoms of 6-22 to modify, the foam inhibiting performance of the defoaming agent is improved.

Effective defoamer compositions contain two different aryl-substituted organopolysiloxanes and filler particles, and show high defoaming capability.
