Freeze dryers are becoming important part of food processing and preservation in modern industries. However, for optimal functioning of freeze dryer, you need the right accessories.
Depending on your freeze drying process, you can choose from a wide range of accessories that may include:
1. Drying Trays
The aim of drying trays is to hold your food products during the drying cycle or process. They are important because they distribute food evenly during the process of freeze-drying. This accessory is ideally made from high-grade aluminum or food-grade stainless steel.
When you buy the best of freeze dryers, the drying trays they come fitted with are made to withstand very low temperatures and vacuum pressure. Also, there are those types that are perforated, which makes it easier for air to circulate well. Therefore, making drying quick.
These trays are
- Easy to clean and sanitize
- Ensure you have uniform drying
- Durable
- Can be reused
2. Tray Lids
Tray lids are also a valuable accessory your dryer will come with. It prevents cross-contamination. It also prevents the condensation of moisture.
Your tray lids will cover drying trays. This is important to ensure that your products are not contaminated by moisture or foreign particles from other parts of the machine. These lids help to maintain the integrity of your product, particularly for high-sensitivity items such as pharmaceuticals or dairy products.
Some unique benefits of this accessory is:
- Aids in maintaining the structure and shape of the food.
- Ensures contamination or dripping is prevented
- Makes it easier for you to stack without damaging product content
3. Tray Stackers
Tray stackers make it easier for you to have well-organized and smooth productions. This accessory organizes and stacks trays to perfection. Also, these stackers make it possible for multiple trays to be stacked securely in the drying chamber.
If you run an industrial-scale company, this will be very great for you. This is because it helps to increase your chamber space and throughput. Some other benefits they bring include
- Enhanced your productivity levels
- Increases the chamber capacity of your freeze dryer
- Enhances even airflow between layers
4. Shelves
Shelves offer your freeze dryer the right adjustable support for its trays within the chamber. You will find these shelves either built-in or removable. They help to keep a specific distance between drying layers.
You can decide to choose from those shelves that have built-in heating features. This will ensure your products have even heat distribution during the sublimation stage.
Some clear gains of this accessory are
- Had customizable spacing
- Promotes the transfer of heat
- Able to support heavier loads without warping
5. Tray Dividers
The main purpose of tray dividers is to separate the different types of food or different batch sizes on a single tray. Dividers aid in tray segmentation. This is beneficial if you will require different food items dried at the same time without contaminants or mixing flavors.
Dividers mostly come made of food-grade stainless steel or silicone. You can trust these dividers to:
- Offer you batch flexibility
- Make your yield and inventory tracking easier
- To prevent mixing or shifting products
6. Drying Chamber
Drying chambers enclose trays and create a unique vacuum for sublimation. Although it is a part of freeze dryers technically, specialized or upgraded drying chambers are able to enhance operational efficiency. Mostly, these drying chambers come with features such as anti-fog viewing windows, dual-door access, or LED lighting.
All these helps to enhance its inspection and usability. Some more unique benefits you get with using them include
- Clear visibility when operating
- Ensures a sealed environment for the best drying is provided
- Enhances the safety of your workers and monitoring
7. Filter Systems
Filter systems ideally maintain that clean air and vacuum conditions. Mostly, you will find freeze dryers coming either with oil mist or HEPA filters to trap all airborne particles, contaminants, and oil vapors. This means, they do not enter or exit the freeze dryer.
Clean air is vital to maintain high quality and food-grade standards. Some specific benefits they come with include:
- Enhances hygiene
- Extends the life of your equipment
- Ensures food contamination is prevented
8. Vacuum Pumps
Vacuum pumps create that vacuum necessitated to ensure freeze-drying is perfectly achieved. These pumps are ideally reliable and powerful accessories that can be found at the heart of any freeze dryer. These accessories mostly include cold traps, oil-free pumps, and pump silencers.
You can decide to upgrade to a quieter model or higher capacity. This will significantly enhance its performance. Also, you get to benefit in the following ways:
- Cuts down processing time
- Ensures faster pressure drops
- Different energy-efficient models are available
9. Tray Mats
Tray mats mainly protect trays and prevent food from getting stuck on them. Tray mats are PTFE coated sheets or silicone sheets placed on trays. They are washable, non-stick, and reusable.
When you use these mats, dried food is easy to remove without breaking or scraping it. Other benefits to note down include:
- Makes your cleaning simple and easy
- Preserves the texture and shape of the food
- Enhances the lifespan of trays
10. Silicone Molds
Silicone molds consistently shape food portions before the drying process. You can make use of them for drying products like yogurt drops, fruit puree, or pet treats. The silicone molds they come with allow for pre-freezing foods in the same sizes.
This also enhances consistent drying and final products that are attractive. Also, silicone molds bring these added benefits:
- Reduces your waste
- Ensures drying is even across all batches
- Promotes professional presentation of food products
11. Drain Hoses
Drain hoses remove water and condensate from the freeze dryer. These hoses are designed to help you in evacuating melted ice or condensate from the drying condenser or chamber. The right drainage is vital to maintaining hygiene and preventing floods.
Added benefits of drain hoses
- They are easy to maintain
- Prevents chamber floods
- Enhances equipment longevity
12. Mylar Bags
Mylar bags are purposely designed to be able to store your dried food to ensure they have an extended shelf life. These bags come with oxygen absorbers. Therefore, they are perfect for storing freeze-dried products.
Again, they protect foods against direct light, air, and moisture. This means your food products can be preserved for longer periods. Mylar bags come in different sizes and are perfect for commercial packaging.
Other benefits of these bags
- They are made to resist puncture
- Highly food-safe
- Has custom-print options to meet your branding needs
- Long-term storage solution
Conclusion
If your company is into food preservation through freeze drying, ensuring the right accessories are used is important. Remember, you need these accessories to make your freeze dryer work to perfection.
