Plant Hire

We have four membrane filtration plants for hire as well as a small spray dryer. We can also provide complete guidance from installation right throught to implementation into your production line. To enquire about hiring these facilities, please contact us.

Membrane Filtration Plants

We have two pilot plants suitable for laboratory or experimental work, and two production plants.

Pilot Plants

Membrane filtration is typically sized by the total surface area of the membranes. Our two pilot plants have a surface area of 0.09m², and 0.18m².

Both plants:

• Can take micro-filtration (MF), ultra-filtration (UF), or nano-filtration (NF) membranes, and we carry the membranes in stock.
• Have been constructed using food-grade quality materials.
• Use hollow-fibre membranes to allow for ease of cleaning, and although neither can be cleaned in place (i.e. they are not "CIP-able"), they can both be cleaned to food-grade standards.

Production Plants

Our two production-size plants have total membrane surface areas of 4.6m² and 12.2m².

The 4.6m² plant is:

• A nano-filtration (NF) plant with pre-filtration to about one micron.
• Constructed from food-grade quality materials.
• Can be cleaned-in-place (i.e. it is "CIP-able") to food-grade standards.
• Contains two 3-inch spiral-wound membranes each with a surface area of 2.3m².
• Approximately NZ$1700/month (plus GST) to hire, depending on what is required to interface with your current production line.

The 12.2m² plant is:

• An ultra-filtration (UF) plant capable of product-processing.
• Constructed from food-grade quality materials.
• Can be cleaned-in-place (i.e. it is "CIP-able") to food-grade standards.
• Contains two 5-inch hollow-fibre membranes each with a surface area of 6.1m².
• Approximately NZ$4000/month (plus GST) to hire, depending on what is required to interface with your current production line.

Spray Dryer

We have one small spray dryer for hire:

• Niro "Production Minor" spray dryer.
• Water evaporation rate of approximately 12 kg/hour with 200°C inlet temperature.
• Electric air heating means there will be no nitrates or nitrites in the final product.
• The inlet temperature can range from 120°C to 350°C.
• Either a rotary nozzle or a two-fluid nozzle can be used.
• Equipped with explosion ducts and an automatic water-deluge system in case of fire.
• Both inlet and exhaust air temperature can be automatically controlled via a PLC-based programmable system.
• We are in the process of adding:
  • A New Zealand Food Safety approved pasteuriser for dairy products (incorporated into the feed system).
  • An air broom.

The spray dryer is currently used by our subsidiary, Pearl Ingredients. If you are interested in spray drying your product, or experimenting to see if spray drying is the right solution for you, then please contact Pearl Ingredients, who will be happy to discuss your needs.

If you are interested in hiring the spray dryer then please contact us.
