American Custom Drying

American Custom Drying (ACD) is a leading U.S.-based toll manufacturer and custom spray drying specialist with over 60 years of industry experience. Operating facilities in New Jersey and Pennsylvania, the company serves both food and non-food specialty ingredient markets, having processed more than 1,100 distinct products across its history. ACD positions itself as America's largest silo storage provider for spray drying, with capacity to store up to 350,000 gallons of liquid feedstock in stainless steel silos equipped with heating and agitation systems.

The company's core service is converting liquid materials into shelf-stable powders through custom spray drying. It operates seven spray dryers of various sizes, including food-dedicated and soft chemical-dedicated units, with campaign sizes starting as low as 500 pounds. Customers benefit from the ability to conduct pilot-scale trials — batch sizes as small as 20 gallons — before scaling up to full commercial production, minimizing risk and optimizing process parameters prior to large runs.

Beyond standard spray drying, ACD offers microencapsulation services, using high-shear and homogenization techniques to encapsulate flavors, fragrances, vitamins, minerals, and lipids. Oil loads of up to 70% are achievable depending on the carrier system. The company has also expanded into spray chilling and prilling — also known as spray congealing or melt atomization — which transforms molten materials such as waxes, hard fats, hydrogenated vegetable oils, polymers, phytosterols, and hydrated salts into uniform, spherical solid particles. This capability is particularly valuable for taste masking, controlled-release formulations, and improving the flow properties of sensitive ingredients.

Liquid batching is another key capability, with jacketed tanks featuring precision temperature control for chemical reactions, customizable setups using heat exchangers, filters, and pumps, and onsite silos that directly supply batch rooms. Bulk packaging options include super sacks, drums, pails, and poly-lined bags, with inline metal detection and bulk density control to ensure correct fit into desired packaging formats.

ACD serves a broad range of industries including food and nutraceuticals, cosmetics and personal care, and chemical and industrial markets. Its onsite analytical laboratory supports quality control through protein and nitrogen analysis, particle size analysis, bulk density, ash, moisture, pH, viscosity testing, and more.

On the certifications front, the company holds SQF 2000 Level 2 certification under the Global Food Safety Initiative (GFSI) at both its NJ and PA facilities, is ISO 9001 compliant with a documented record of zero non-conformances across five years of surveillance and recertification audits, and maintains full HACCP certification compliant with GMP standards, 9CFR417, and 21CFR110 regulations. These credentials make ACD a reliable outsourced manufacturing partner for companies requiring rigorous food safety and quality management standards.
