Case Study:

Freeze Dryer for Milk Kefir Powder Production. This process involves freeze drying as a key technology in creating powdered milk kefir.

Customer: The Grain Factory Pte Ltd

The Grain Factory Pte Ltd, a Singapore-based company specialising in fermented health products, was looking for a reliable solution to scale its probiotic product production. Their goal was to convert liquid milk kefir into a stable probiotic powder while maintaining quality and nutritional value using freeze drying for optimal results.

To achieve this, they adopted our freeze dryer machine, designed specifically for food and probiotic processing.

Challenge

Before implementing a freeze dryer, The Grain Factory faced two major challenges through their freeze drying process.

1. Short Shelf Life

Liquid kefir has a very limited shelf life and requires refrigeration at all times. This made storage and distribution difficult, especially for wider markets, and emphasized the importance of careful freeze drying.

2. Difficult Shipping and Logistics

Shipping liquid kefir without refrigeration was nearly impossible. Maintaining the cold chain increased costs and limited their ability to expand distribution. The freeze drying method offered a promising solution.

They needed a solution that could:

• Extend product shelf life
• Preserve probiotics and nutrients
• Enable room-temperature storage
• Produce a stable powder form for packaging and distribution

Solution: Freeze Dryer Machine for Probiotic Production

The company implemented our freeze dryer machine to convert milk kefir into probiotic powder.

Freeze drying works by freezing the product and removing moisture through vacuum sublimation, allowing the structure, nutrients, and probiotic cultures to remain intact throughout the freeze drying cycle.

Our PM500 freeze dryer machine enabled them to:

• Transform liquid kefir into fine probiotic powder.
• Preserve probiotic activity
• Extend shelf life significantly
• Package and ship the product without refrigeration

The machine is specifically suitable for freeze drying dairy products, probiotics, and functional food ingredients.

Results

After adopting the freeze dryer, The company successfully produced high-quality kefir powder suitable for consumer products.

Key benefits included:

• Stable probiotic powder production
• Longer shelf life without refrigeration
• Easier global shipping and logistics.
• Consistent production quality

The freeze dryer machine allowed the company to move from fragile liquid products to a more scalable powdered format.

Customer Feedback

After using our freeze dryer machine, the user shared the following feedback:

“The product dissolves well in the mouth, and the machine is performing according to the desired outcome. Other machines can only produce grain-like results, not a fine powder like this one.” In fact, freeze drying is the step that makes this fine powder possible.

This demonstrates the capability of our freeze dryer to produce high-quality, fine probiotic powder, which is essential for premium food and health supplement products.

Applications of Freeze Drying in Food Production

This case shows how freeze drying technology can support modern food businesses by enabling the production of freeze drying based products.

• Probiotic powders
• Functional food ingredients made possible
• Dairy powders such as kefir and yogurt
• Nutritional supplements
