I Application

The blenders are used to mix solids in liquids. In the food-processing industry, they provide a perfect solution for reconstituting powdered milk, making syrups, preparing brines, etc. They can also be used for preparing solid-liquid mixtures in the pharmaceutical, cosmetics and chemical industries.

I Operating principle

The blender basically consists of a casing and a centrifugal pump impeller which are mounted vertically. The suction side has a double-wall pipe that keeps the inlet of solids separate from that of liquids, thus avoiding the formation of lumps before the material enters the casing. The liquid enters the mixing chamber at a high speed, thereby creating a vacuum at the center of the impeller, which causes the suction of the solids. The introduction of solids can be regulated by means of a valve situated at the bottom of the hopper.

I Design and features

Simple and versatile assembly for quick and homogeneous mixing of a great variety of solids without contact with the air. Complete mixing with recirculation of the product In some applications, it can be used in line, without recirculation. Sanitary design. Easy assembly and disassembly by Clamp connections. Cleaning can be carried out without disassembling the unit. Sanitary internal single mechanical seal. Standard hopper of 40º for M-226 and 50º for M-440.

I Applications

Preparation of sugar syrup, sorbitol, glucose, lactose and derivatives. Reconstitution of powdered milk. Dissolution of cocoa and/or sugar in milk. Reconstitution of powdered whey. Preparation of flour and starch slurries. Preparation of brines. Pre-mixtures of yogurt and other milk-based desserts. Dissolution of bentonites for wine filtering. Dissolution of casein and caseinates in the cheese-making industry. Preparation of pesticides and fertilizers.

The quantity of the suctioned product depends on its properties and the features of the installation. Please, contact INOXPA technical department to select auxiliary pumps.

It is important to keep low pressure at the suction and at the dishcrage sides of the blender and avoid cavitation. Thus, a feeding pump must be provided only for the applications that really require it (considerable pressure drops at the suction side, high viscosity products, etc.), please, keep in mind that the suction capacity will decrease. When discharge pressure is high, a centrifugal pump needs to be fitted to the discharge side of the blender. For viscosities above 500 cP, the feeding pump and the discharge pump must be positive displacement pumps.
