About dry sift hash screen

Types of dry sift hash screens

The dry sift hash screening process uses several mesh screens with differing mesh sizes. Each type of screen has a specific names, uses, and specifications.

  • Micron sieve screen: Micron sieve screens are mesh screens with specific holes that allow certain trichomes or cannabis crystals to pass through while retaining the plant material. They have precise measurements of the micron diameter, such as 220U, 200U, and so on. The smaller the number gets, the smaller the holes become. Other micron mesh screens include 160U, 120U, 90U, 75U, and 25U. Each micron mesh screen creates different types of hash powder.
  • Dry sieve hash screen: The dry sieve hash screen refers to multiple mesh screens in a sieving box. The screening box collects the sifted cannabis crystals, including the dry sieve hash bags and the collecting box. Typically, the dry sieve screening box first uses the 220U or 160U mesh screen to separate the fine dust. The intermediate mesh screens, like 120U, 90U, and 75U, separate valuable cannabis crystals. Finally, the bigger particles are extracted using the 25U mesh screen. In the screening box, some plant fragments remain on the mesh screens. The whole process is called the dry sieve method.
  • Hash bag screen: The hash bag mesh screens are often placed in mesh bags. Buyers need to pay attention to the specifications, as the bag usually narrows at the bottom to make a funnel-like shape, which is convenient for people to collect the final products. The mesh sizes of the hash bag screens are the same as those of the dry sieve hash screens. In the case of the hash bag, people usually see the 110U, 90U, 70U, and 25U mesh screens.
  • Triangle mesh screen: The triangle mesh screens have a triangular aperture and a specification of T20. The triangular apertures create a larger opening than square mesh of the same size. The triangular mesh screens are often utilized to replace the 220 microns and larger mesh openings to enhance air flow during sifting.

Specification and maintenance of dry sift hash screens

Specifications

  • Mesh size:

    The dry sift screening mesh size represents the specific size of holes within the screening fabric. It directly correlates with the particle dimensions that the sieve is constructed to separate. For instance, a hash screen with a 160-micron mesh size will permit particles measuring 160 microns or more to pass through, while smaller particles will be trapped.

  • Material:

    Typically, dry sift hash screens are manufactured using nylon or polyester, synthetic materials renowned for their resilience and capacity to sustain precise mesh apertures. Certain industrial-grade screens may incorporate stainless steel wire, which offers exceptional durability and uniformity.

  • Screen dimensions:

    The screen's dimensions, encompassing its length and width, are dictated by the sieving equipment or container's proportions in which it is utilized. Screens may be found in a wide range of dimensions, from small squares to large rectangular shapes, to suit distinct sieving needs and equipment sizes.

Maintenance

  • Kind of clean:

    Users can clean the screen of dry sift hash by softly tapping or shaking it to eliminate the majority of the collected plant material. This procedure will reduce the bulk of the material on the screen and make further cleaning more manageable.

  • Brush:

    A gentle brush can be used, such as a paintbrush with soft bristles or a specialized screening brush. Users should lightly reverse the screen's side to brush it, ensuring that the screen's pores are not damaged and that only a small quantity of material is discarded on the other side.

  • Cleaning solvents:

    Be cautious not to use any cleaning solutions or chemicals on the screen, as they can contaminate the final product. Avoid using excessive water or any solvents that could clog the mesh holes.

  • Storage:

    When not in use, users should store their dry hash screens in a dry and clean environment away from sunlight or high temperatures. Consider using a protective cover or bag to prevent foreign objects from contaminating the screen.

Industry Applications of Dry Sift Hash Screens

Dry sift hash screens are widely used in the cannabis industry, with numerous applications in hash making, separating material, and sieving processes.

  • Dry sift hash extraction: Sift hash screening is very popular in the cannabis industry, acting as the mainstay of dry sieve extraction. High-quality dry sift screening can separate trichome glands from plant material without using water or solvents, making it an invaluable tool for obtaining dry sift hash.
  • Quality control:Dry hash screens can be used for sieving excess material in the final products. By sieving with different mesh sizes, one can Identify and remove contaminants, such as mineral and plant debris, improving the purity and quality of the final product.
  • Flooring and pavement industry: Dry sieving screens are used in the flooring and pavement industry to separate undesired materials from final products, such as fillers, ashes, and other aggregates. For example, in epoxy floor production, dry sift screens can be used to separate fibrous materials from the mixture, resulting in a smoother final product. Similarly, in asphalt production, the screens can help remove undesirable materials to enhance the pavement's quality and durability.
  • Industrial sieving:Industries such as food, pharmaceuticals, and chemicals may employ hash screens for sieving and separating products. Dry sift screens with specific mesh sizes are utilized to separate, for instance, herbal medicine, spices, or chemical compounds, to improve product purity and quality.
  • Education: Dry sift hash screens are also used in an educational setting to demonstrate the sieve technique's principles and applications. For example, educational institutions may use these screens to teach particle separation techniques, raise students' awareness of the importance of purity and quality in different industries, and foster their hands-on skills and experimental abilities.

How to choose dry sift hash screens

  • Quality of mesh material:

    The quality of the mesh material used in dry sift hash screens makes a big difference in yield and potency. Screen materials should be strong but still flexible to maintain consistent extraction.

  • Durability of frame:

    The frame shape and material are equally important for durable screens. Frames made from corrosion-resistant metals or sturdy wood provide a long-lasting structure that can withstand heavy use without bending out of shape.

  • Sizes:

    Dry sift hash screens come in a range of sizes to suit different extraction needs and available workspace. A smaller screen may be more portable and easier to store, but it could limit the quantity of material processed at one time. Conversely, large screens provide the capacity to extract more kief in a single session, yet they require more space and are less convenient to transport.

  • Number of screens:

    Many dry sift hash screens feature multiple levels, each with its own mesh to capture kief of varying grades. Having several screens in one device allows for a more thorough extraction process where even the finest particles are sifted and collected separately.

  • Screen mesh sizes:

    Different screens have varied mesh dimensions, affecting which kief particles can pass through into the next screen. Using multiple mesh sizes improves purity by ensuring only high-quality resin heads make it into the final hashes.

    Generally, larger mesh sizes tend to filter out more plant matter, while smaller ones capture more kief but might also retain some contaminants.

Dry sift hash screen FAQ

Q1: Why are different mesh sizes important in dry sift hash screens?

A1: Different mesh sizes are crucial in dry sift hash screens because they allow specific particles to pass through while retaining others. As described above, smaller mesh sizes capture finer trichome heads, while larger ones let more plant material pass through.

Q2: Can users wash dry sift hash screens?

A2: Yes, they can gently wash the dry sift screening using a mix of isopropyl alcohol and salt. After soaking, users can use a brush to get rid of any remaining contaminants or debris, then rinse it thoroughly.

Q3: What is the difference between dry sift and wet hash extraction?

A3: The main difference between the two kinds of hash is that in dry sift hashing, the product is extracted without using water. On the contrary, wet hash extraction involves water and ice in the extraction process.

Q4: What is the purpose of dry sift hash screening?

A4: A dry sift hash screen's mesh fabric or material is used to separate fine resin from dried plant materials. In most cases, this process occurs by sieving or milling material across the mesh.
