Yamato DL410 Large Capacity Spray Dryer



Yamato’s DL410 large capacity spray dryer produces fine particles from 1 to 100μm, which is considered to be extremely difficult to produce in laboratories. This spray dryer does not require samples to undergo pre or post processing such as filtration, separation, or pulverization. Furthermore, the spray dryer ensures efficient and quick drying of small, expensive, and heat sensitive samples with its easy operation.

Our DL410 spray dryer is useful for preliminary tests for pilot plant or expensive samples, micro capture spray drying research, as a substitute for general laboratory drying methods, and much more. Organic solvents are also supported with the attachment of GAS410 organic solvent recovery unit.


  • Liquid sample or solution is not required to undergo any pre or post processes such as filtration, separation, or pulverization
  • Small, expensive and/or heat sensitive samples can be dried quickly and efficiently
  • Processes samples as small as 0.5g of solid matter
  • Safe for heat-sensitive samples, such as food or medical products
  • No risk of contamination within the spray dryer
  • Digital display of inlet/outlet temperature and drying air volume
  • Detachable drying chamber, cyclone and product vessel
  • Fast and easy clean up
  • The hot air inlet and drying chamber cover automatically move up and down, and since the cyclone and product vessel can easily be removed, cleaning and maintenance of the spray dryer after experiment is easy
  • Control functions are conveniently arranged on the control panel for various conditions
  • Temperature recorder, air flow meter, pressure gauge and other measurements allow easy control of experiment conditions
  • Universal power supply and multi-lingual touch screen controller

Spray Dryers

Spray drying equipment has improved over the years. Today, you can process products from milk powder to antibiotics using spray dryers. Yamato’s spray dryer models are suitable for experimental and R&D purposes. You can use our spray dryers for drying, fine powdering, powder mixing, agglomerating, encapsulating, and englobing.

Commercial Food Products

Spray dryers were used widely during the Second World War to produce milk powder. Hence, it is no surprise that the largest market for lab spray dryers nowadays is in the food industry particularly in powdered milk and instant coffee production.

From milk production, the use of spray drying technology has extended to the production of powdered varieties of coffee, algae, gum arabic, protein hydrolysates, yeast extract, starches, and non-dairy creamers to name a few.

You can now rapidly create agglomerates or powder from liquids such as emulsions, suspensions, and solutions since spray dryers are fully-automated and continuous. Moreover, spray drying equipment such as the ADL311SA—a Compact & Economical Spray Dryer by Yamato—are highly suitable for drying both heat-resistant and heat-sensitive foods, allowing shorter residence time with no oxidation and minimal moisture remaining.

Spray drying is also used for encapsulating active substances, homogenizing these into slurries or emulsions before drying. By encapsulating food products, you get to protect your product from heat degradation and therefore improve final product functionality.

Pharmaceutical Products

Not all medical dosages are soluble. Hence, spray drying technology affords the pharmaceutical industry an economical and fast alternative to converting liquid feed into powdered medications and additives such as extracts, infusions, inorganic medicinal salts, vitamin C, and adrenaline.

Since the 1940s, the use of spray drying equipment in pharmaceuticals has advanced from simple drying methods to sophisticated processes such as the production of excipients like ointment bases and preservatives and the isolation of active ingredients that are either hard-to-crystallize or heat-sensitive.

Needless to say, spray drying is an ideal process for those requiring precise attributes especially in the morphology, stability, and particle size of your pharmaceutical products.

In just a single continuous process, you get to convert liquid feedstock into a well-defined powder and get desired properties including precise residual solvent, moisture level, particle morphology, as well as density and size of particulates, which is crucial in the pharmaceutical industry. With high-performance spray dryers like the Yamato DL410 Large Capacity Spray Dryer, you can produce fine particles with sizes from 10 to 100 micrometers, which are considered by many to be difficult to achieve.

Furthermore, you are guaranteed a contaminant free powder with minimal moisture and zero oxidation, so you can guarantee patrons that your products are safe.

Industrial Products

Aside from food and pharmaceutical production, spray dryers are essential for the industrial creation of powdered materials such as catalyst supports, ceramic materials, microalgae, detergents, and paint pigments.

Used, basically, for encapsulation by most industries, applications of spray drying equipment in an industrial setting includes the production of not just powders but also textiles, adhesives, pesticides, carbonless copy paper, and anti-corrosive coatings just to mention a few. The microencapsulation technique involves the use of coatings such as polyvinyl alcohol, sodium alginate, starch, and gelatin.

By encapsulating, you get to reap numerous benefits; one is an extended shelf life for your product and another is increased stability. On the other hand, you also get to decrease the evaporation of the volatile core in products such as paints and pesticides. Aside from those, you also get to reduce oxygenation, prevent a chemical reaction, and improve handling properties of adhesives.

Now, if you are spraying acidic samples for either aqueous or organic solvent, before exhausting to environment or recirculating to the GAS410 Solvent Recovery Unit, we recommend using the GWS410 Organic Solvent Washing Unit to neutralize the air or gas which contains acidic ingredients.
