A cashew drying machine is industrial batch drying equipment that removes moisture from shelled cashew kernels through controlled hot-air circulation. The machine featured on this page is Shuliy’s drying room for cashew processing, a sealed box-type dryer built from stainless steel. It processes 300 to 8,000 kg of cashew kernels per batch, depending on the model, and lowers kernel moisture to a stable level for shelling, storage, and export.
Compared with sun drying, this cashew nut dryer delivers uniform temperature, adjustable humidity, and all-weather operation. It prevents mold, discoloration, and flavor loss while making cashew shells brittle enough for clean cracking. For processors building or expanding a cashew line, it offers a cost-effective way to improve kernel yield and product value.
Shuliy has supplied food drying equipment to buyers in over 30 countries for more than 20 years. Each machine is backed by installation support, operator training, and a one-year warranty with lifetime technical assistance.
Why Cashew Processors Need a Dryer?
Les noix de cajou fraîchement décortiquées contiennent beaucoup d'humidité. Si elles ne sont pas séchées à temps et de manière approfondie, cela peut entraîner :
- Croissance de moisissures et contamination bactérienne
- Couleur assombrie et goût moins bon
- Durée de conservation raccourcie
- Absorption d'humidité et détérioration de la saveur
- Difficulté à enlever la coque
L'utilisation d'équipements de séchage professionnels garantit que chaque lot de cajous atteint le niveau d'humidité approprié, assurant un goût et une apparence constants.

Key Features of OurCashew Drying Machine
Sealed Stainless Steel Chamber
The chamber and trays use corrosion-resistant 304 stainless steel. This protects kernels from contamination, meets export food-hygiene requirements, and allows fast cleaning between batches.
Precise Temperature & Humidity Control
A PLC controller manages drying temperature, airflow, and cycle time automatically. Operators set the curve once and the machine maintains stable conditions throughout the batch.
Forced Hot-Air Circulation
High-power circulating fans distribute heated air evenly across every tray layer. Top, middle, and bottom trays dry at the same rate, reducing rework and tray rotation.
Flexible Heat Sources
Choose air-source heat pump, electric heating, sulfur-free coal, or hybrid energy. Heat-pump operation typically cuts energy use by 30–50% compared with pure electric heating.
Modular Capacity
Units from SL-2 to SL-24 share the same core design. Start with a small industrial cashew dryer and expand later, or choose a larger model for full commercial output.
Compact Footprint & Quick Installation
The box-type structure needs no complex civil works. Most models arrive pre-assembled and can be installed and commissioned within one to two days.
How the Cashew Drying Machine Works?
- Loading: Spread shelled cashew kernels evenly on stainless steel trays. Do not overload; airflow must reach every layer.
- Heating: The heat source warms air inside the sealed chamber.
- Circulation: Circulating fans push hot air through the trays. Moisture evaporates from the kernels.
- Dehumidification: A humidity-controlled exhaust fan removes moist air while fresh dry air enters.
- Cooling & Unloading: Once moisture reaches the target level, kernels cool inside the chamber before shelling or packaging.
Typical drying conditions for cashew kernels: 50–65°C air temperature, controlled humidity, and 6–14 hours per batch, depending on initial moisture and target level.
Cashew Processor Pain Points & Solutions
| Pain Point | Solution Shuliy | Result |
|---|---|---|
| Kernels mold before processing | Fast batch drying in sealed chamber | Longer safe storage |
| Uneven color and taste | PLC temperature and humidity control | Consistent product quality |
| High shelling breakage | Controlled moisture reduction makes shells brittle | Higher whole-kernel yield |
| High electricity bills | Air-source heat pump option | 30–50% energy savings |
| Weather-dependent production | All-weather indoor drying | Predictable output year-round |
Drying Room vs Mesh Belt Cashew Drying Machine
For most cashew processing plants, the box-type drying room is the right choice. It offers lower investment, simple operation, and flexible batch sizes.
For very large-scale continuous lines that run 24 hours a day, a mesh belt dryer may be worth considering. This continuous conveyor dryer feeds and discharges automatically and handles several tons per hour. You can read more about it on our continuous conveyor dryer page.

Pourquoi utiliser une machine de séchage de noix de cajou ?
Séchage plus rapide, efficacité de production accrue
La circulation d'air chaud accélère l'évaporation de l'humidité, raccourcissant considérablement le cycle de séchage et facilitant l'augmentation de la production. Idéal pour les usines de taille moyenne à grande.
Séchage uniforme pour une qualité de produit plus stable
Un contrôle précis de la température et de l'humidité empêche le sur-séchage, le sous-séchage ou la décoloration, garantissant une couleur et un goût constants des cajous.
Décorticage plus facile, rendement en noyaux plus élevé
Les coques de cajou séchées deviennent plus cassantes et leur teneur en humidité diminue uniformément, facilitant l'écaillage, réduisant la casse, et améliorant le rendement en noyaux entiers.
Indépendant des conditions météorologiques, traitement toute l'année
Une qualité de séchage cohérente est assurée, quel que soit la saison pluvieuse, humide ou chaude, rendant la planification de l'usine plus prévisible.
Assure l'hygiène alimentaire, adapté à l'exportation
Un environnement de séchage fermé empêche la contamination par la poussière et les insectes. La construction en acier inoxydable renforce encore la sécurité alimentaire.
Réduit les coûts de main-d'œuvre, améliore l'automatisation
Minimise les opérations manuelles telles que le retournement, le déplacement ou le séchage au soleil, économisant du travail et évitant les incohérences de qualité causées par des facteurs humains.
Conception écoénergétique, coûts d'exploitation réduits
Une bonne isolation et une circulation d'air chaud améliorent l'utilisation de la chaleur, réduisant la consommation d'énergie tout en maintenant l'efficacité.
Prolonge la durée de conservation et la compétitivité sur le marché
Une teneur en humidité stabilisée après séchage empêche la formation de moisissures et la détérioration, assurant un stockage et un transport plus sûrs, et renforçant la compétitivité sur le marché.

Yes. We supply English manuals, video guides, and online support. On-site engineer service is available for an additional fee.
What spare parts should I keep in stock?
We recommend keeping circulating fan belts, heating elements, and temperature sensors as backup parts. Shuliy supplies original spare parts with fast dispatch.
Can I dry other nuts in the same cashew drying machine?
Yes. The same drying room handles peanuts, almonds, walnuts, macadamia, and seeds by adjusting the temperature and time curve.
What is the typical payback period for a commercial cashew dryer?
Most processors recover the machine cost within 12–24 months through reduced spoilage, higher kernel yield, and year-round production.
Do you provide samples or test drying services?
Yes. We can arrange test drying records and videos from our facility so you can evaluate kernel color, moisture, and texture before purchase.
