The table blender is used to dissolve solids / powders in recirculated liquids. It has a wide range of applications, for example, preparation of pharmaceutical syrops or dissolution of pectin in glucose for marmelade production. Every model has an option with an in-line mixer for a complete dissolution of possible lumps. The typical applications are reconstitution or stabilization of milk in the production of dairy products, and dissolution of sugar for the production of syrup in the beverage industries.
Operating principle
The table blender is a compact unit, it consists of a centrifugal pump with a venturi system at the suction side and a hopper with a butterfly valve at the upper part to add solids / powders to the pumped liquid. In this blender, the suction and ventury system are set horizontally. If necessary, an in-line mixer can be installed after the centrifugal pump to reduce the size of possible lumps.
The venturi system and the suction of the pump create depression at the base of the hopper. When the valve of the hopper opens, the solids are drawn from the hopper and are totally dissolved when they pass through the casing of the pump.
To achieve the best possible dissolution, it is recommended to recirculate the product (batch production) till all the solid / powder product is suctioned and then, when the solid product is completely incorporated into the liquid, continue recirculating the product for a while. In some cases, the blender can be used in-line depending on the solid product to add and the required level of dissolution.
