KTH-Air RECYLING TARAR -

Tue, 31 Mar 2026 11:32:30 +0000

The closed circuit aspirator type KTH is a cleaning machine that separates light impurities found in cereals. The machine may be divided into three main components:

Vibrating box: this is a feeding box attached to the machine body by six rubber mounts and vibrated by a motorized

vibrator.

- Body: in its upper part it houses 2 impellers driven by an electric motor and in its lower part it houses a waste products discharge

screw connected to a air lock seal.

- Outlet hopper: this is fixed to the lower part of the machine body.

Via gravity spouting the product enters into the vibrating inlet box and is forwarded and distributed thanks to the vibratory

motion and the particular configuration of the

internal product distribution blades.

During its fall into the hopper beneath an air stream passes through the product flow for separating light parts (waste product). Suction is produced by the negative pressure generated by the two impellers housed in the top section.

Aspirated waste is dragged by the air stream into a decantation zone, from where it falls and a collection screw conveyor

takes it to a sealed airlock valve. At its outlet the waste is fed directly to the offal spouting. The machine is provided with an air bleed for partial air recirculation and for maintaining inside the

condition of negative pressure.

Dough kneading groups

Tue, 24 Mar 2026 17:28:26 +0000

Rigel Machine ltd. is able to produce various configurations of dough mixing units to meet the specific needs of each pasta factory.

Our experience in designing and producing mechanical systems enables us to work on existing installations, to adapt them according to the company’s latest demands and enhance the existing units with new accessories to meet new production requirements.

Here are some of our products:

The centrifugal pre-kneader with automatic dosing system is a machine which is commonly used in pasta production to create dough mixes using the best methods, mixing semolina (or other flours) with water, egg and other ingredients, in the right quantities, such that any type of pasta can be produced using this mixing unit. The purpose of the pre-kneader is to blend and mix the ingredients so that the liquids are uniformly distributed, hence improving the quality of the dough.

Its automatic system enables the continuous production of dough mixes without the need of an operator present, guaranteeing low energy consumption and high productivity.

The functioning of the pre-kneader is fairly simple, an upstream screw feeder dosing system, complete with bridge breaker, allows for the regulation of the quantity of ingredients prior to mixing; the unit fea-tures tangential injection of liquids (water and egg). The blending of the ingredients is achieved using a paddlewheel rotor with an unloading outlet at the base of the unit.

In addition, the unit is fitted with an electronic volumetric dosing system suitable for incorporating extra ingredients.

TECHNICAL FEATURES

A machine made entirely of stainless steel and equipped with the following apparatus:

Container for flow of flours and powders, complete with safety standards and bridge breaking stirrer shaft
High precision volumetric screw feeder dosing system in stainless steel for flours and powders
Volumetric dosing for water/liquids
Pre-blending cylinder with screw feeder, can be disassembled for cleaning
Main centrifugal blending cylinder fitted with a bladed shaft which can be disassembled for cleaning

· Centrifugal pre-kneader par

-Centrifugal pre-kneader has made the process of hydrating flour, traditionally performed by paddles inside the kneading tank, obsolete. Thanks to the innovative system for dosing dry and liquid ingredients, it makes it possible to produce different kinds of pre-kneaded dough in an automatic, flexible and continuous way. Specifically conceived for the sectors of dry and fresh pasta, couscous, gnocchi, bakery products, it can be installed on all kneading tanks, presses and dough sheeters.
