Raw material feeding
Fruit or vegetables are fed into the de-stoning machine after washing and preparation. Depending on the line configuration, the raw material can be loaded manually or supplied from a washer.
De-stoning machine
De-stoning machine for fruit, vegetables and stone fruit
Industrial de-stoning machine for separating stones, skins and solid parts from pulp. It enables the preparation of uniform fruit and vegetable pulp used in the production of juices, purees, jams, mousses, sauces and other food products.
What is it used for
What is a
de-stoning machine used for?
The de-stoning machine is used to separate raw material into finished pulp and a separated waste fraction, such as stones, skins or larger solid parts. This makes it easier to prepare a uniform product for the next processing stage.
The machine is suitable for processing stone fruit and soft fruit, such as cherries, plums, apricots, peaches and strawberries, as well as tomatoes and selected vegetables. Thanks to replaceable perforated sieves, the de-stoning machine can be adjusted to the raw material and the expected structure of the finished product.

How a de-stoning machine works
2
Processing through a sieve
The raw material is rubbed through a properly selected perforated sieve. Depending on the product type and expected structure, sieves with different perforations can be used.
3
Separating pulp from stones and skins
The working system separates pulp from stones, skins and larger solid parts. This makes it possible to obtain uniform pulp or puree ready for further processing.
4
Receiving the finished pulp
The finished puree goes to a tank, pump or another device in the production line. Separated stones, peels and waste are discharged separately, which helps maintain continuous operation.

Feed hopper
It allows fruit and vegetables to be fed conveniently into the machine and directs raw material smoothly into the working chamber.
2
Replaceable sieves
Sieves with perforations from 0.5 to 10 mm allow the structure of the finished product to be adjusted. The pulp is pressed through the sieve and separated from stones, skins and larger fractions.
3
Working rotor
It pushes the soft fraction through the sieve while moving stones, seeds and larger parts toward the outlet. It is responsible for effective separation of pulp from the remaining fractions.
4
Safety sensor
It prevents the machine from starting if the chamber has not been properly secured after replacing the sieve or opening the cover. It increases operating safety and protects the operator during work.
5
Stone/seed outlet
It removes stones, seeds, skins and other harder parts separated during processing. This helps maintain continuous machine operation.
6
Transport wheels
They make it easier to move the de-stoning machine and position it conveniently at the workstation. This is a practical solution, especially during washing or line reorganization.

After washing and preparation, the raw material goes to the de-stoning machine, where valuable pulp is separated from stones, peels and solid parts. The finished pulp can then be directed to a process tank, pasteurizer or filling machine. This machine arrangement makes it possible to build an efficient processing line for purees, mousses, sauces and fruit or vegetable semi-finished products.
Frequently asked questions
How much does a de-stoning machine cost?
The price of a fruit and vegetable de-stoning machine usually ranges from approx. 5,800–9,300 EUR net. The final price depends on the machine configuration, sieve type, equipment and how it will operate in the processing line. We prepare a detailed offer after determining the raw material and the expected structure of the finished pulp.
What capacity does the de-stoning machine have?
The capacity of the de-stoning machine is up to approximately 1,000 kg/h. The actual throughput may depend on the type of raw material, preparation level, ripeness of the fruit or vegetables and the sieve used. During one 8-hour shift, the machine can process up to approximately 8,000 kg of raw material.
What raw materials is the de-stoning machine suitable for?
The de-stoning machine is suitable for processing most stone fruit and selected vegetables that require separation of pulp from skins, stones, seeds or larger solid parts. It can be used, among others, for cherries, plums, apricots, peaches, strawberries, tomatoes and other raw materials intended for pulp, mousses, sauces and purees.
Does the de-stoning machine separate stones, skins and solid parts from the pulp?
Yes, the de-stoning machine separates pulp from stones, seeds, skins and larger solid parts. Thanks to this, the finished product has the form of uniform pulp or puree, which can be directed to a tank, pasteurizer, filling machine or further processing.
What sieve can be used in a de-stoning machine?
The de-stoning machine can use sieves with perforations ranging from approximately 0.5 to 10 mm. The sieve is selected according to the raw material and the expected structure of the finished product. Finer perforation gives a smoother puree, while larger perforation works well when the product should retain a more noticeable texture.
What is the lead time?
The lead time for a de-stoning machine is usually 2 to 4 weeks. The exact date depends on current production load, selected sieve, machine configuration and the scope of adaptation to the customer’s process.
What is the warranty period for the de-stoning machine?
We provide a 36-month warranty on the welded structure of the de-stoning machine. For purchased components, such as motors, automation elements or other components, the warranty period is usually from 12 to 24 months, depending on the component manufacturer. After the warranty ends, we provide post-warranty service and access to spare parts.
Do you provide service for de-stoning machines?
Yes, we provide de-stoning machine service, technical support and access to spare parts. We help with machine start-up, sieve selection, setting the machine for a specific raw material and solving problems that may arise during operation.
Can I see how the de-stoning machine works before ordering?
Yes, before purchasing you can see how the de-stoning machine and the entire processing line work. We work with plants that use our machines, so we can arrange a meeting during actual production. Presentations are possible depending on the availability of a given plant and the machine operating date.
What is the payback time for a de-stoning machine?
The payback time of the investment depends on the type of raw material processed, the scale of production, labor costs and the value of the finished puree. With a capacity of up to approximately 1,000 kg/h, the de-stoning machine can process up to approximately 8,000 kg of raw material during one 8-hour shift, which significantly improves the production of pulps, mousses and purees compared to manual work or less efficient solutions.
