The product design philosophy of PETKUS Batch Treaters combines form and function. The shape of the stator is conical, tapered and equipped with deflectors. The seed is purposefully directed back into the stator center. The stator itself is optional lined with a synthetic material that reduces product adhesion and offers a self-cleaning effect. The electro-polished rotor and its smooth stainless steel surface also prevent chemical or polishing agent adhesion. The dosage of the chemical agent and additives is done via inductive flow meters. The seed is assigned by means of a precision electro-pneumatic batch scale and gravimetric dosing.

The application and seed quantities are measured continuously, and thus the actual and target values are compared and automatically adjusted during an ongoing process. The various application recipes can be saved. Each treated seed lot is logged with an “Application History” and can be secured and documented externally via USB storage.

The MultiCoater works according to the rotor-stator principle. Seed is loaded into the mixer batch-wise. The dosing of the chemical agent and additives is done via inductive flow meters. The seed is fed in by means of a precision electropneumatic batch scale and gravimetric dosing. The chemical agent and seed quantities are measured continuously and thus the actual and target values are compared and automatically adjusted throughout an ongoing process. A perforated spraying disc creates an extremely fine dispersion of the chemical agent at a wide spraying angle.  The rotor and stator are made of smooth, electro-polished stainless steel, so there is no chemical agent residue adherence. Deflecting elements made of plastic, with a form similar that of an aircraft wing draw the seed into the middle in an optimized and aerodynamic manner, ensuring excellent mixing.

The highlight of the MultiCoater is its sophisticated air management. Air passes through nozzles and an adjustable gap between the stator and rotor. This creates an air cushion between the stator wall and the seeds which dramatically reduces the friction stress. Towards the end of the coating process the air flow rate can be, increased in order to further dry the seed. Coated seeds do not need to be dried in another process step.
