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 compact PETKUS DF dryers dry product as it flows over zig-zagged levels, based on the vibrating fluidized bed principle. Counterbalance motors create a consistent and uniform vibration, while the air ensures a homogenous flow of goods. Warm air is blown in through two separate and adjustable flaps by a fan located at the side of the dryer and flows through the product in an upward motion. Four temperature sensors allow for optimal monitoring and control of the drying process.

Characteristics

• Flexible, efficient & gentle drying
• Compact design and small footprint due to z-shape drying loop

The PETKUS Belt Dryer was developed to gently and flexibly dry seed after chemical treatment. During the coating process large amounts of liquid are sometimes sprayed leading to moisture pick-ups of up to 5%. Fluctuating weather conditions or high humidity also influence moisture content thus making seed drying an inevitable step to preserve germination capacity and improve sowability / flowability.

Warm air is fed from the side through 2 hot air channels by 2 separate fans allowing air to flow through the product homogeneously from below. The temperature can be individually regulated. Four temperature sensors allow for optimal monitoring and control of the drying process thus preventing product from overheating and preserving germination capacity / vigour. The PETKUS Belt Dryer ensures that desired optimal residual moisture levels can be realized. Warm air flows through the fluidized product and absorbs moisture as water evaporates from the surface of the kernels. The moist air then flows onward through the air outlet.

Characteristics

• Preserves germination capacity & improves flowability
• Efficient & gentle drying
• Individual temperature control
• Variable product flow speed
• Temperature sensors for continuous monitoring and control
• Reduced abrasion and improved Heubach values
• Integrated automatic belt cleaning (optional)
• System for recycling used water

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.

The 200L cylindrical mixing tank contains an impeller type mixer which is driven by an external bipolar motor. The liquids are mixed intensively at first with a high rotation speed and then mixed gently at a lower speed.

The seed dressing is filled into the mixer through a flap in the cover. Scales with control panels can be integrated to ensure precise weighing of the different liquids. Water can be supplied through a nozzle connection and a float indicates the fill level in the mixing tank. The tank is emptied through a spout located at the base of the tank and the well mixed seed dressing can be pumped directly to the treater.

Characteristics

• Stainless steel mixing tank
• Robust, low-wear construction
• Intensive agitation and mixing of liquids
• Adjustable processing intensity
• Agitator with 2 brush strips
• Variable rotation speed for intensive mixing
• Weighing scales und control terminal optional

During product design, special attention was given to the independent seed dosage and chemical agent dispersion. In the synchronized and extremely precise chemical treatment process the individual grain characteristics are of little importance. The seed is volumetrically metered over the hopper into the generously sized spraying chamber. An even product flow into the spraying chamber is ensured by means of a rotary valve with specially beveled cells. In the spraying chamber the seeds are sprayed by using a rotating distribution disc which creates  an even product veil making it possible to achieve a constant and uniform coating without blind spots even at a high throughput rate. The treating agent is sprayed in a fine mist below the distribution disc, surrounding the product and ensuring an even coating.  In the second mixing chamber, the seeds are thoroughly and intensively yet gently mixed using a back and forth agitating motion from the mixing paddles. A user friendly touch panel makes operating the machine easier and controls the complete treating process.

Characteristics

• Bolted housing made of sheet steel
• Special plastic linings aid in the reduction of product adhesion
• Additional aspiration for the reduction of dust in the spraying chamber
• Precise dosing of liquid seed treating agents and error prevention using integrated automatic control devices
• Control cabinet with touch panel and control software
• Remote Control
• Sensors for monitoring and controlling
• Easy usage, cleaning and handling

The CT Vario is the flexible solution for individual applications. Traditional PETKUS treatment and coating technology and functionality remain intact while allowing for free choice of configuration. The PETKUS design places particular value on precise seed dosing and chemical spraying regardless of the throughput rate. Depending on preference, the seed is dosed gravimetrically or volumetrically in a generously-sized spray chamber. The seed is fed through an optimized and redesigned tangential rotary valve that is particularly gentle. In the spraying chamber, a uniform product veil is created by the rotating distribution disk, even at high throughputs, allowing for consistent chemical application. Eighty percent of the conical spray chamber can be opened, making for easy maintenance and cleaning.

Characteristics

• Modular design for maximum flexibility and variability
• Direct dust removal before treatment via aspiration system
• Precise, reliable and simultaneous wetting and protection of the seed
• Up to 80 % spraying chamber openes for easy maintenance and cleaning
• Accurate and careful seed handling via tangential rotary valve for optimum product dosing
• Self-cleaning secondary mixer
• Chemical treatment with the inclinable Deka-Star Drum Mixer for particularly gentle and efficient handling of the seed
