short-mixer, inter-mixer tech.

[aso]

Здравствуйте всем,
Помогите, пожалуйста, с переводом short-mixer и inter-mixer в таком контексте: (очистка масел)

The acid conditioned and/or heated oil is reacted with lye solution injected at a controlled rate in the Neutralisation Inter-Mixer M2 or in the Neutralisation Short-Mixer M3, depending on the type and quality of the feedstock. The lye neutralises the free fatty acids and the excess of phosphoric acid in the oil forming soapstock which is removed together with excess lye and other impurities in the Soapstock Separator S1.

Спасибо!
