What is Sublimation
Sublimation, in physics, is conversion of a substance from solid to gaseous state without itsâ becoming liquid. The process of drying the products by first freezing them and them removing the ice under vacuum (sublimation of ice) is also often called lyophilization, cryodesiccation or freeze drying

Mushrooms
Sublimated products retain their form and texture and could be rehydrated easily to be used in tasty, nutritious meals
Strawberry
Sublimated products have a unique taste - same as fresh fruits but up to 10 times more intensive. That makes them to perfect snacks, loved by adults and children
Herbs
Sublimated products retain the nutrients and vitamins from the original products, while having a very long shelf life. They could be used in sophisticated and health oriented cuisine
Meat
Sublimated products are up to 5 times lighter than the original ones, while retaining the full nutritional value. They are a perfect companion for adventure trips, tourism, competitive sports.
I would like to share my passion in sublimating apples.
I would like to share my delight in sublimating apples! This process amazed me with its uniqueness and great results. Apples undergo an amazing transformation, turning into light and fragile treats that melt in your mouth. First, the appearance of sublimated apples is great. They have a bright and appealing texture that is eye-catching. Whether it's apple chips or pieces of freeze-dried fruit, every bite looks perfect and mouth-watering.

Sublimated products
Sublimated strawberry
Dried strawberry
not just strawberries dried for longer shelf life, but a whole new product…
For example, fresh strawberries do not look very appetizing when put into yogurt. Sublimated strawberries absorb yogurt and become an integral part of a delicious and attractive-looking morning meal, while retaining all the vitamins and nutrients of the fresh fruit.
Sublimated apple

Sublimation: Possible Business Models
Our sublimation equipment could be used for your private purposes â to preserve your own harvest, or to produce nice and healthy snacks for your four-pawed friend. However, the main reason to purchase our machines is to make a good business with the products they can produce. Below you can find a couple of examples from our current customers. They are happy with our machines and with their new business. We hope you will soon join them, and come up with your own ideas of profitable and healthy business!
Preserving the harvest
Strawberries are a delicate product subject to vagaries of the weather. Once the weather is warm and dry, a lot of strawberries ripen in the fields, and the prices drop. One can choose not to sell at the dumping price to the supermarkets, but rather to preserve the harvest by sublimation. Good quality strawberries make delicious sublimated strawberries, which command retail prices of 120 Eur per kg and more.
Producing the biologically active substances
The gentle drying method allows to retain all the important substances in the dried plants, herbs, flowers, which could be then processed into a powder form and / or encapsulated.
Bar snacks
Salty dried snacks raise thirst and thus go well with a good beer or wine. Furthermore, they simply look good.
Producing the supplies for tourists, sportsmen, adventurers
The sublimated products have the highest nutritient to weight ratio. This is very important for those who need to carry them to remote locations. Furthermore, no cooling is needed for storage, only an airtight package. Thus, sublimated products like meat command very high prices when sold to this target group.
Producing novel snacks
Unique texture of sublimated products and their high nutrient content make them to an ideal basis for all sorts of snacks â sweet and savory. The price is limited only by your creativity, the field is relatively new, and the consumer desire for tasty and healthy snacks is skyrocketing
Making pet food
Dried healthy treats for dogs or cats â made from meat, fish or other ingredients of choice â are a good option to reward them for their loyalty and good behavior.
Providing ready to serve hot meals, like soup or gulash
Sublimated meals are packed in an airtight bowl. Slowly adding hot water is restoring the original texture, color and taste. Freshly cooked meals â anytime, anywhere! No fast food anymore. Sublimated meals is a healthy and convenient alternative!
Preserved flowers, or the whole bouquets
Diamonds are forever, but even the freshest bouquet dies within a week. For those, who want to keep the warm memories of their gorgeous moments (for example, the bridal bouquet), sublimation technology offers the only possible solution. Sealed in a glass jar, the flowers will stay looking fresh and gorgeous for many years.
Sublimated citrus slices are perfect for any bar or restaurant
They could be easily grated to create a powder with intense taste - which could be used to garnish exquisite dishes and drinks
Supplying innovative high value food ingredients and colors
For example, flower petals could be used as colorants, additives, decoration...

Diana
Diana (SIA âDainasâ) grows strawberries. Seasonal product with short shelf life. Big dumping from wholsale buyers also pressed her buisiness…
She purchased an experimental sublimator for 6 kg and began to produce freeze-dried strawberries and freeze-dried strawberry powder
Freeze-dried strawberries are in demand all year round, and are especially popular as gifts for children at Christmas
Freeze-dried strawberry powder is supplied by Diana to several local confectionery stores throughout the year
As a result, Diana doubled the area of greenhouses with strawberries, bought our industrial machine for 50 kilograms and wants to develop furtherâĶ
Inga and Ilze
Inga and Ilze, owners of a small confectionery factory (SIA
“KarameÄžu darbnÄŦca”). At some point, they realized that they had
reached the ceiling of their candy production market
Owners decided to expand the assortment and diversify the
production line and bought a small experimental sublimation
machine
They started sublimating fruit and using it in the production of
chocolate and candy. They saw that the addition of freeze-dried
fruit creates a bright taste and flavor of candies and chocolate
They tried to launch a âspace” line of products
The demand became such a big, that they took a loan and bought a
100 kilogram sublimation machine from us
As a result, sales of new “space” candies and “space” chocolates
have significantly improvedâĶ
Now they are working on a new unique product and are preparing
to buy a 1000 kilogram robotic sublimates production line from
usâĶ
Inetta
Inetta (SIA “PakalnieÅĄi”) produced cottage cheese. There were limitations on shelf life, and the product was not unique….
She have bought 1 experimental machine for 6 kg.
As a result, she created 2 technologies that made her cheese unique:
-production of cheese with freeze-dried additives (mushrooms, vegetables, meat products) and
-production of freeze-dried cheese products with additives, e.g. cheese candies
The economic effect allowed Inetta to purchase a 30 kg industrial sublimation machine from us a year later!
She doesnât want to stop there and is preparing to buy a large 100 kg unit
