S series batch dryer
High-quality and efficient grain drying
The stationary S series dryers by Mepu dry the grain in a gentle, energy-efficient, and reliable even under challenging circumstances. Grain batch humidity does not affect the outcome, since the grain is dried by circulating it through drying cells and equalizing the grain humidity in the top bin so many times that the entire grain batch is fully dry.
S series dryers are based on the same high-quality technology as Mepu’s high-power continuous flow dryers. In addition to advanced drying technology, reliability and ease of use have been emphasized in the dryer design.

Features
BOTTOM THROUGH
The steep and smooth-walled bottom through ensures that the grain falls on the bottom auger in all conditions, resulting in a carefree drying process. It’s easy to clean the bottom through from the large maintenance hatch.
FEEDING APPARATUS
The rollers with adjustable speed ensure that the grain is circulated evenly in all conditions and with all grain types. The continuous adjustment/opening mechanism of the bottom hatches enables uncrushed grain to be fed to the apparatus, with different grain types.
The feeding apparatus can be cleaned easily, using the maintenance hatches located on the sides, and through the bottom hatches that can be opened.
AIR DUCTS
The internal surface of air ducts is smooth, so that grain does not become stuck on the surfaces, and the maintenance need is low. The optimized surface area of the air ducts ensures that the drying result is energy-efficient.
Large maintenance hatches enable maintenance works to be performed quickly and easily. Any grain that has been blown to the air chambers will be returned from both sides, back to the feeding apparatus, thus reducing the cleaning need of the air chambers.
ElevaTOR
The almost maintenance-free, efficient and silent bucket elevator ensures that the dryer is filled and emptied quickly. The elevator can be positioned flexibly to the dryer, making the positioning of the dryer easier. There’s a 3-way divider at the elevator top part, which you can use to change the grain flow to the dryer or away from it.
GRAIN BIN
The durable and smooth-surfaced grain bin ensures that grain flows into the drying cells even in wet and demanding conditions, ensuring that the drying process is trouble-free..
DRYING CELLS
The mixed-flow drying cells ensure that the air and the grain is mixed efficiently, resulting in a smooth and energy-efficient drying result. The drying cells stay clean thanks to their smooth internal surfaces, making maintenance work quick and effortless.
PRE-CLEANER AND SPREADER
The pre-cleaner fitted with a spreader (S3 and S4 models) spreads the grain evenly in the grain bin, filling the grain bin efficiently, as well as cleaning the grain from any rubbish and dust.
FANS
Highly efficient centrifugal or axial fans ensure that the drying result is cost-effective.
HEAT SOURCE
The efficient overpressure or negative pressure furnaces ensure that the drying result is cost-efficient.
CONTROL PANEL
A simple and logical control panel is included in the standard delivery, which makes the dryer easy to use.

READYMADE-grain dryer
Since 1983, Mepu has been constructing ready-to-use batch dryers according to customers' wishes.
Mepu's READYMADE concept is available for all dryers manufactured by Mepu, where the dryer is delivered electrified and nearly ready for installation. Motors and cable harnesses with connectors are pre-installed. Pre-assembled drying units, grain bins, and the cover with railings expedite the construction process. The heater, automation, and all essential components for commissioning are included in Mepu READYMADE deliveries.
Modern Drying Technology
Mepu's drying technology is energy-efficient, reducing operational costs. The heat sources used for drying ensure a high-efficiency ratio. You can choose between the BASIC/SEMI-automatic control panel or the AUTO-automatic control panel with continuous moisture measurement and remote control. The moisture measurement is accurate and reduces the costly risk of over-drying or under-drying, achieving the desired moisture level, rain or shine!
The variable frequency drive for the axial fans reduces electricity consumption, and the stepless adjustment of air volume optimizes the drying air temperature. With the optional insulation package, energy consumption is low, drying is more efficient, and you can save up to 10-20% on energy costs.
Mepu READYMADE dryers do not require special transportation. Construction and commissioning happen quickly. Resale value is well-known to remain high. Mepu dryers are known for their long service life and low maintenance and spare parts costs.
