Part of $50 million investment, state-of-the-art belt dryer offers benefits over spray drying, including moisture evaporation at lower temps
Saddle Brook, NJ – Malt Products Corporation (MPC), a manufacturer of malted barley extract and other natural, nutritious sweeteners, has invested over $15 million in a new state-of-the-art drying plant, incorporating a vacuum belt dryer designed and built by drying technology expert Bucher Unipektin. The 58-foot-long machine has completed installation and validation, and is currently operating at the company’s Dayton, OH manufacturing facility.
MPC chose the vacuum belt dryer over a spray dryer because of its superior ability to produce free-flowing particulates of viscous sugar syrups, as well as retain flavor, aroma and color. Since vacuum belt drying operates by reducing the pressure in its chamber, moisture is evaporated from the product at far lower temperatures. This eliminates oxidation and prevents damage to critical functionalities of the original syrup.
Important to the drying of malted barley extract, vacuum belt drying utilizes a gentler process that protects unique-to-product characteristics not found in other sweeteners, including antioxidants, essential amino acids, minerals and vitamins. Vacuum belt drying also helps avoid burnt notes or other off-flavors and aromas typical with spray drying, and better controls the maillard reaction for a more consistent final product color.
Vacuum belt drying produces a powder that is highly soluble in cold liquids, making it preferable for malt beverages. The enhanced technology will allow MPC to manufacture products such as honey, agave and molasses that are difficult or impossible to dry on a spray dryer without additives.
The initiative also has an eye toward eco-consciousness: vacuum belt dryers use less energy and water than spray dryers, reducing environmental impact and aligning with MPC’s broader commitment to sustainability.
The new dryer is part of a five-year, $50 million investment by MPC, beginning with the 2015 expansion of its state-of-the-art brew house and addition of a Meura mash-filter, expanded laboratory, research and development and customer application capabilities. These investments are in response to increasing demand for non-GMO and natural, nutritious ingredients.
There has been a growing and renewed interest in MPC’s malted barley extract because of its unique flavor profile and recognition of its health-related benefits in the field of probiotics, plant-derived proteins, sports recovery and antioxidants. MPC’s malted barley extract is a multi-functional ingredient that acts as a natural humectant (moisture absorber), and enhances browning, fermentation, body and viscosity.
Malt Products Corporation also supplies a broad spectrum of healthy, natural sweeteners including molasses, oat extract, rice syrup, tapioca syrup, agave and honey.
“The new drying plant will continue our commitment to supply natural sweeteners which are minimally processed and environmentally sustainable”, said Amy Targan, President of MPC.
Malt historically has been an attractive ingredient in pet food and animal feed for its whole grain derived nutritional contributions. Some of the more common associations with malt include:
Minerals: including calcium, copper, magnesium, manganese, potassium, selenium and zinc. Copper and seleni-um are integral as antioxidant enzyme co-factors which help shorten recovery in sporting and working dogs.
From malt extract, B Vitamins: (niacin, riboflavin, pantothenic acid, thiamin, nicotinic acid, Vitamin B6 (pyridoxine), biotin, and folic acid). Vitamins are primary cofactors in metabolism and formulating with vita-min containing ingredients helps aid energy production and utilization in animals that consume them.
Protein and amino acids: malt extract contains ~6% protein and free amino acids which are nutritional compo-nents required for building and maintaining muscle tissue. Physical exertion increases the need to rebuild and reinforce muscle fibers, and the presence of protein and amino acid helps in this regard.
Pallatability: Malt contains compounds that help improve the overall flavor profile of petoods and that can mask bitter tastes.
