Avocado Vacuum Dehydrator
Engineered to address avocados’ dual challenges of nutrient richness and heat-sensitive oxidation, the SIMEC Avocado Vacuum Dehydrator employs revolutionary Low-Temperature Rapid-Dehydration (LTRD™) technology to lock in 98%+ of nutrients, even at 1/3 the time of conventional drying methods.
Technology introduction:
Low-Temperature Avocado Vacuum Dehydrator consists of biomass heating system, heat flow circulation system, vacuum chamber, material tray support, control system and other necessary accessories.
The biomass heating system runs on biomass pellets or macadamia nut shells. It automatically controls heat flow temperature within a set range. With automatic feeding and temperature control, it cuts heating costs. Plus, it shrinks the carbon footprint during avocado dehydration.
The vacuum chamber, made of food-grade stainless steel, is a sealed space for drying. In vacuum, the boiling point of water drops, enabling low-temperature dehydration and preventing oxidation. The tray support with heat-flow pipes evenly heats the vacuum chamber. Well-designed and strong, it can hold 96 trays, greatly increasing throughput.
The control system is equipped with advanced sensors to monitor both the heat-flow temperature and the chamber temperature in real-time. It then automatically and precisely adjusts the heater output, ensuring that the chamber temperature remains stable within a pre-set range.

Technical advantages:
1. Low Temperature Dehydration Retains Nutrients.
Under the vacuum condition, the boiling point of water drops significantly, enabling the moisture within the avocados to swiftly vaporize even at a very low temperature, thereby achieving efficient dehydration. This process maximally preserves the original nutritional value of the avocados.
2. Vacuum Environment Prevents Oxidation.
Oxidation darkens avocados, spoils their flavor, and deactivates nutrients like antioxidants. In a vacuum environment, the minuscule oxygen content effectively stops avocados from oxidizing. Extra Virgin avocado oil can be extracted from vacuum-dehydrated avocado pulp using an avocado oil cold press machine.
3. Circulating Heat Flow Ensures Uniform Dehydration.
The circulating heat flow system is distributed throughout the vacuum chamber, forming an all-round heating structure to ensure uniform temperature. Avocados in the upper, middle, and lower layers of the vacuum chamber can all be dehydrated in the same temperature and pressure environment, which ensures that each piece of dried avocado has consistent color, taste, and water content. Avocados can be dehydrated efficiently at low temperature.
4. Eco-Friendly Process.
It’s a low energy consumption, low carbon footprint process for dehydrating avocados.
5. Large-Capacity Design.
SIMEC avocado vacuum dehydrator can dehydrate avocado paste and sliced avocados. It has a large capacity and enables quick loading and unloading of materials.
