Presently, more than 100 different varieties of hazelnut products are created and distributed to markets around the world. Therefore, it is imperative that emphasis be given to the creation of novel hazelnut-based goods. Products made from hazelnuts can be categorized into a number of broad categories based on the hazelnut's root, wood, trunk, stem, bark, blossom, and fruit. food items: All sorts of nuts, chocolate, edible oils, hazelnut flour, hazelnut paste, hazelnut cookies, hazelnut biscuits, hazelnut slices, enriched pasta, enhanced bread, flavored dairy goods, flavored ice cream, gum, jelly, and other goods are included. 
Medicinal Cosmetics: The extraction of potent compounds, various vitamins, Taxol anti-cancer tablets and capsules, hazelnut leaves and stems-based antimicrobial goods, topical oils, various lotions, sprays, perfumes, etc.—are all included in this process. Inventive uses for discarded hazelnuts: It contains things like fuel, activated carbon, dye-absorbing substances, nourishment for animals and birds, nanobiological fertilizers, natural colors, and crafts made of hazelnut wood, among other things. a description of how new Fandouq goods are made and processed: 1- Hazelnut butter and oil As we all know, hazelnuts contain roughly 60% oil, which is light yellow in color, has a mild flavor, and is also pleasantly scented. It is used in cooking, perfumery, and painting. 
In factories that produce oil, these are the typical steps:
- Degumming
- Neutralization
- Drying
- Decolorization
- Hydrogenation
- Decolorization again
- Oil formulation
- Deodorization
2- Hazelnut paste: Hazelnut paste is one of the newest products made from hazelnuts that is frequently utilized in the food sector. This hazelnut-derived product has a high added value and is used in a variety of food industries, including the production of chocolate, flavored dairy products, cakes, biscuits, cookies, and muffins, confectionery, different kinds of caramel, flavored bread, enriched pasta, etc. It also has industrial applications. The pre-milling and ball mill are parts of the production line for hazelnut paste. Hazelnuts are ground to 110 microns during pre-milling, and the final product is ball milled to 20 to 30 microns. The tank and storage both have two layers, as well as the ball mill, which has a two-layer cover. Cold water is automatically dispensed during this operation. This machine has an hourly capacity of 800-100 kg. Hazelnut peeling machine: The hazelnut's green peel is initially separated from it after it has been harvested (pod). This task was previously carried out manually and in the old-fashioned way, which was exceedingly time-consuming and inefficient. The hazelnut peeler not only removes the green skin from the hazelnut but also does it in a perfectly hygienic and very effective manner, separating the resulting skin and pods from one another. 
Hazelnut nut remover: The de-seeding machine can efficiently and with a low rejection rate de-seed seeds with hard skins. This machine can manage this operation adequately and does not require pre-sorting of the seeds, regardless of the size of the incoming seeds. Serand device: In various sectors, a tool is required to sort produced goods according to their sizes. By swapping out the plates for the equivalent mesh, Serand offers flexibility in changing the output product's granulation (mesh) size. Cracker for producing hazelnuts: After Turkey, the United States, and Spain, Iran is one of the world's top hazelnut producers. Salted hazelnuts are more well-liked than nuts from other countries among Iranians. It is necessary to soften the hazelnut before salting it, unlike its comparable product, the pistachio, which has a naturally smiling shape. Hazelnuts have previously been cracked manually and traditionally by pounding them between two hard objects (such as stones), which has a number of drawbacks including being unhygienic, time-consuming, having a high turnover rate, lacking staff during the peak of demand, and not having a permanent workforce (mainly rural women turn to this work during idle times and to earn a small amount of money). This issue has been resolved by the beaming hazelnut machine through an extremely hygienic and productive method (less than 3 percent waste).
- Hazelnut chocolate
The components of chocolate are combined and refined in the chocolate grinder (sugar powder, vegetable oil and hazelnut powder). 
The system, which is built of stainless steel, moves and stirs the inner layer. The system automatically receives cold water at the appropriate time. This approach will result in chocolate with a thickness of 2–25 microns when 50 microns of powdered sugar are utilized. The product's grain size will range between 20 and 25 microns, depending on the flow rate. Repurposing leftover chocolate: Reprocessing used chocolate is an essential step in the creation of natural chocolate. Due to heat transmission and mechanical stirring, the viscosity of the chocolate is reduced throughout this procedure. Moreover, this technique eliminates moisture, volatile substances, and offensive scents. Six steps make up waste preparation, which takes about 13 hours: (1) loading preparing dry chocolate waste, preparing plastic chocolate trash, preparing chocolate waste, and homogenizing 6 Electrical discharge 4- Extraction and purification of effective ingredients of hazelnut: Hazelnuts are the only fruit, as far as we are aware, that contains all 20 of the essential amino acids required by the human body. 
The nutritional and therapeutic value of this fruit is also enhanced by the presence of vitamins from the B1 and B3 families. So one of the key issues to think about when creating new goods from hazelnuts is extracting and purifying the beneficial components. These facilities include those for chemical analysis laboratories. ,
- The manufacture of activated carbon:
One of the materials with several applications is hazelnut skin. As raw materials for creating activated carbon, a variety of organic plant, synthetic, and natural substances with a high carbon content can be used, particularly cellulose byproducts like lignin. Since activated carbon has a contact area of 250–300 grams per square meter, it may efficiently absorb all types of chemical contaminants from the gas or liquid phase, including dyes and heavy metals. Applications for activated carbon include: 1. Dye removal 2. Getting rid of heavy metals 3.Treatment of wastewater and water.
