Hemp is a delicate crop and has to be handled with care. For its use in the pharmaceutical industry, the preservation of the oil is essential. The CBD essential oil is unable to be extracted from the resin within the leaves and fibres if the product has a moisture content that is higher than 10%. However, if heated and dried too quickly, the oil can be damaged and less valuable.

Hemp is one of the most versatile crops that we process. The seeds (the inner kernels of the plant) have a range of uses in the food industry. Once dried, the seeds are then often sold whole as a health food, or they are cold pressed for the production of nutritious oil.

 

As such a delicate crop, it is important that it is processed promptly to prevent the growth of mould and fungus that could greatly damage the plant. This is where an Alvan Blanch Hemp Drying System has benefits beyond other methods. A simple loading system means the plant can be immediately fed into the hemp dryer, and the drying process begins straight away – there is no manual labour or delays, such as those found within a drying room method. The effective, but gentle processing of an Alvan Blanch Hemp Drying System ensures the maximum levels of CBD are retained.

Alvan Blanch Hemp Drying Solutions:

Alvan Blanch design and manufacture a range of Hemp Dryers. These dryers work around the needs of our customers, suited to a variety of capacities. With highly efficient drying at low temperatures, our Hemp Dryers ensure that plant breakage is reduced.

One of our Hemp Dryers is our Conveyor Dryer model. As the most versatile in our range, the CD is optimised for the drying of hemp. The design of the CD means the crop is moved along the dryer bed by several product agitators, as a result, non-free flowing products are easily conveyed through the dryer.

The speed at which the product moves through the dryer is controlled with the variable speed drives. The main spinner at the feed section of the dryer allows the user to adjust bed depth from the initial loading. These hemp drying systems start from 10 metres and go up to 50 metres long, depending on capacity demands and footprint.

Alvan Blanch Hemp Dryers are capable of handling very wet products, in particular our Rotary Dryer range. Suitable for those who are looking for an efficient dryer in a smaller footprint. This range of Hemp Dryers have an almost a completely automated operation, with a low energy consumption.The Alvan Blanch Hemp Dryer range gives the user complete control of the machine settings. This allows for control of the conditions and a more consistent process that ensures the quality of the end product.

Hemp Seed Drying:

The Alvan Blanch Hemp Drying System is also suitable for the drying of hemp seeds. As a popular product in the food industry, drying is an essential step to ensure the safety standards of the product. As the product is free-flowing, the Double Flow works as an efficient Hemp Seed Dryer. The unique louvered bed moves the seed along the dryer at an even and controlled bed depth. The Hemp Seed Dryer’s conveying system eliminates the possibility of hotspots and blockages, minimising any potential damage that could be caused.

Hemp Seed

As with other dryers in the Hemp Drying Systems range, the Hemp Seed Dryer has a gentle process; with several features that make it effective even at low temperatures, mostly due to the balanced air flow. The cooling section, in the bottom bed, allows the seed to be cooled properly before storage. This section is also capable of recovering the waste heat from the dryer.

Our Hemp and Hemp Seed Dryers can be run on a variety of heat sources, including the waste heat from a biomass boiler. These varied heat sources ensure the environmental impact of the drying system is greatly reduced.

Alongside our unique drying systems, we also provide a range of processing equipment designed to work in conjunction with our hemp dryers. This includes a complete range of conveying equipment and post-drying bailing and bagging solutions.

Versatile Drying Control Systems

Alvan Blanch offers both relay logic control and PLC (programmable logic controller) systems for the range of dryers. We aim to improve our user friendliness and offer a control system that has remote control built into it, so that dryer settings can be adjusted by iPad, iPhone, Android and similar.

In particular, with our upgraded PLC system, the dryer operator is able to view a different screen as to the dryer supervisor, while the supervisor’s screen reflects latest remote operation happened on the machine. In addition, fault-finding diagrams are built into HMI and machine manual so as to facilitate the operations. With regard to the data storage, PLC internally stores key values with date and times stamped, which can be used for future operational analysis and comparison.
