Application

Table mixers for viscous products are used to incorporate solid ingredients into liquid products circulated by a centrifugal and a lobe rotor pump. The range of applications include applications like incorporation of solid ingredients into viscous sauces and incorporation of pectins into glucose in jam production. An in-line mixer can be installed right after the centrifugal pump to break up lumps.

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 solid product to the pumped liquid. Optionally, a mixer can be installed right after the centrifugal pump. And a lobe rotor pump is installed after the mixer.
The ventury system and the suction of the pump create depression at the base of the hopper. When the valve of the hopper opens, the solid ingredient is drawn from the hopper and is totally dissolved when it passes through the casing of the pump.
When the product starts getting thicker, it is the lobe rotor pump that maintains the flow of the liquid, thus maintaining a high level of the solid ingredient absorption capacity.
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 product, continue recirculating the product for a while.
In some cases, the table blender can be used in-line depending on the solid product to add and the required level of dissolution.
