Advanced Walnut Drying Lines

NutVision Advanced Drying Lines are built to produce Superior nut quality and energy efficiency through ow temperature drying without compromising on drying time. They have been designed with superior engineering and operational knowledge using the highest level of technology in the market today. With NutVision Advanced Walnut drying Lines, we are committed to give:

Highest Product Quality

Thanks to its advanced design and technology, NutVision Walnut Dryers operate at significantly lower temperatures, between 30 - 34 degrees Celcius, while still being able to finish their cycles around an average of 24 hours (depending on your location, clilmate and the moisture level of the walnut at harvest. Low temparature drying is proven to improve taste, color, protect chemical composition and nutrient values of the walnut.

Energy Efficiency

NutVision Advanced Drying Lines are designed to consume less gas and electricity per each ton of walnut dried. Each client project is designed specifically with the particular weather parameters observed in the project site during the harvesting period.

DPC - NutVision Drying Process Controller

An efficient drying system relies on constant data collection and making of minor adjustments. Thanks to our touch screen "Drying Process Controllers" installed both on floor as well as bin levels, NutVision drying systems make these adjustments for you, constantly, reliably.

Automated, computer controlled loading gates,
Individual accummulated drying time registers for each bin,
Auto shut-off timer programmable for each bin, each line or the entire drying system,
Integrated moisture level sensors on each bin - upper and lower.
Bin full/empty sensors
Humidity, temperature, CO and CO2 sensors gathering real-time information of the drying room as well as the outside.
Integrated conveyor and gate controls, that allow single button control for the entire nut flow
Integrated, remotely accessible touch screen Drying Process Controller in two levels operating in 3 languages.
Visual and Audio warning system for the operator

Heating & Energy Efficiency

One of the key elements that differentiates NutVision drying systems to other systems in the market is the fact that they operate in lower temperatures while still minimising drying cycles and energy used per unit of dried walnut.

Our unique approach to air delivery allows us to prioritise precision of airflow and drying room air circulating, reducing the need to increase air temperature, reducing energy used.

While the speed and working load of every electrical motor and heater can be reduced electronically, this electronic reduction usually results in inefficiencies below a certain load. Thanks to our individual fan system for each bin and our Tandem Heaters in each drying line, all controlled by our custom designed "Drying Process Controller", NutVision drying systems always maximises energy efficiency.

Our drying systems are designed to be controlled by or own DPC - Drying Process Controller, that watches information coming to up from the lines and continuously readjust the drying parameters.

Autonomous Operation

An efficient drying process requires strict management of many parameters that needs to be adjusted during the drying operation. DPC - Drying Process Controller, NutVision´s own dedicated computer analyzes information received from over 300 sensors and makes minor adjustments in system parameters continuously. Each dryer bin, independently, works for the time set and stops automatically when their jobs are done, without the need for any operator, even when you are asleep. This not only eliminates operator errors but also lowers your labor costs.

DPC also manages the fresh air and exhaust system of the drying room to make sure that the most efficient source of air is provided to the dryers at all time throughout the day, by observing and analysing constantly the relative humidity in and outside of the drying room as well as CO (Carbon Monoxide) and CO2 (Carbon Dioxide) levels to ensure labor safety, contolling autonomously room ventilators and gates.

Our unique approach to Walnut Drying

Fast and uniform walnut drying requires precise engineering work. NutVision Walnut Drying Systems are designed to use a higher air flow-rate compared to almost all other brands, and comes with technologies that allows precise levels of air to be delivered to each of your drying bins, resulting in a fast, uniform and cost effective drying operation. Our bins are equipped with many technologies that makes them run in full autonomy mode.

Air Delivery

Precise air delivery to each bin is the key to uniform drying. To ensure this we rely on technologies and innovative engineering that standardise the amount of delivered air to each bin at all times, rather than making estimates or operating with averages. It is the air passing through the layers of walnut that removes the moisture away and in every NutVision Drying Line, heat is only used, when needed, to reduce the relative humidity of the air delivered, ensuring a fast, low-consumption drying process.

Standardised high air-flow rate for each bin.
DPC - Dryer Process Controller managed two-level, speed controlled air intake fans for each line, operating according to the number of bins in drying mode, determining the optimum air intake of the drying line.
A much higher rate of efficiency compared to conventional "single fan" drying lines that rely on reducing the fan speed, creating serious inefficiencies at less than full load.
