Determining the quality of milk fat dispersion in a jet-slot milk homogenizer

Abstract

the production of most dairy products [1, 2]. The purpose of homogenization is a dispersion (reduction) of the average diameter of fat globules (ADFG) of milk from 3-4 μm in nonprocessed milk to 0.75-0.85 μm in a finished product. Such values correspond to dispersion characteristics of valve 1. Introduction Milk homogenization improves the taste of dairy products and extends their shelf life, so it belongs to standard operations used in the dairy industry. It is conducted in

Increasing the Homogenization Efficiency of the Jet-Slit Homogenizer of Milk

“…The results of analytical studies of JSHM confirmed by experimental studies indicate the possibility of obtaining a product whose ADMFD is 0.75-0.85 μm [11,46]. At the same time, the energy costs of dispersion are 0.70-0.80 kWh/t [47,48].…”

“…At the same time, the course of the process below the liquid level allows avoiding the phenomenon of foaming. Nevertheless, according to the results of analytical studies, the SEC of such a device is 1.3-1.5 kWh/t [11,40]. Relatively high values of electricity consumption of this design are explained by additional energy consumption.…”

“…The advantages of this approach include the possibility of developing predictably energyefficient structures [5,9]. The introduction of homogenizers, the principle of operation of which is based on the implementation of this principle, allows reducing the energy costs of dispersion by 50-60% [9][10][11]. Various types of jet milk homogenizers meet the listed standard.…”

“…Various types of jet milk homogenizers meet the listed standard. According to researchers [9,11], their use ensures a reduction of ADMFD to 0.75 μm. The SEC of such designs is 0.90-1.80 kWh/t.…”

“…Research conducted in [9,11] shows the results of using the principle of separate feeding of skimmed milk and cream. One of such designs is little-studied jet milk homogenizer with a counter feed of cream.…”
