Dry sift screens

Types of Dry Sift Screens

The dry sift technique for cannabis separation relies on the use of dry sift screens or mesh screening to separate trichomes from plant material. Different screen types of dry sift screens are available.

• Snow Frosted Screen

  A snow frosted screen usually has a white or frosted coating on the wires, giving it an appearance like newly fallen snow. This coating serves to enhance the screening material's durability and resistance to wear, ensuring that it can maintain its functional quality for an extended period. This type of frosted screen is easy to wash and collect after use, while the coating improves durability.

• Metal Mesh Screen

  Dry metal mesh screens remain popular in the cannabis industry. They are more durable compared to nylon screens. Metal mesh screens are usually built from aluminum, stainless steel, or other alloys. Their lasting attributes make them suitable for extended use, even under demanding conditions. This durability translates into lower replacement needs and costs over time.

• Mini Micro Mesh Screens

  The mini micro mesh screen presents an opportunity to uncover more fine dry sift. Its smaller holes facilitate the capture of smaller trichomes, contributing to enhanced purity and potency levels in the final product.

• Pulley Screens

  The pulley screen is distinguished by its new kind of pulleys that automatically fix the screen. A significant benefit is simple screen removal and replacement.

• Nylon Mesh Screens

  Nylon mesh screens have variable mesh hole sizes. They are less durable than metal screens, but they offer better sound filtration and can be utilized in sound-sensitive applications.

• Rainbow Sift Screens

  Rainbow sift screens come in different colors. They can be traditionally painted or powder-coated in any color. The aesthetic appeal of rainbow sift screens allows people to show their style and personality.

Specifications & Maintenance

Dry sift screens are available in different specifications to suit distinct filtering needs. They are designed to undergo several types of maintenance to ensure that they function efficiently over an extended period. Some general maintenance tips include careful handling when washing and drying to avoid rips or tears in the mesh fabric. Doing this helps to maintain the quality of the material. Another great way to maintain dry sift screens is to see if there are any build-ups or residue on the mesh. If found, they should be removed gently.

• Material

  Dry sift screens are made with various materials to suit distinct extracting needs. The mesh fabric is usually made with either nylon, polyester, or stainless steel. The frame material can be wood, aluminum, or stainless steel. Choosing a durable material for both the frame and mesh ensures that the dry sift screens can be used for a long time without frequent replacements.

• Cleaning

  It is important to clean dry sift screens regularly to maintain their quality. Residue build-up on the mesh can affect its ability to filter effectively. A gentle cleansing routine involves soaking the screen in warm water and mild soap to break down any residue. Rubbing it gently with a soft brush can help remove any stubborn residue without damaging the mesh. After this, the screen should be rinsed thoroughly to ensure that there is no soap left on the mesh. In some cases, in-depth mesh cleaning may be necessary. A degreaser can be used to break down build-up on the mesh. Isopropyl alcohol can be used for stubborn residue or resin deposits. It dissolves the residue, making it easier to clean the mesh without damaging it. Once it's dried, the residue should be wiped off with a paper towel.

• Storage

  Storing dry sift screens properly helps maintain them and prevents damage. They should be stored in a flat, dry place. Keeping them away from direct sunlight or extreme temperature can help prevent damage to the mesh fabric or frame. If the frame is made of wood, it should be kept away from moisture to prevent mold growth.

Scenarios

There are several application areas where dry sift screens are useful. Here's a brief description of some of the key usage scenarios.

• Dry Sift in Cannabis Industry

  In the cannabis industry, dry sift screens are useful for separating trichomes from plant material to produce quality cannabis concentrates. The screens come in different mesh sizes to separate weed powder or sift,Full Melt, which consists of pure glands, contaminants like leaves and stems, or bag residue,Partial Melt, consisting of full Gland and stalks, and no Glands, no Melt which consists of little to no gland material. Cannabis producers use multi-screen mesas to perform fractional filtration. Each grade of sift hash can fetch a different price in the market.

• Pharmaceuticals Industry

  In the pharmaceutical industry, dry sift screens are useful for sieving fine chemicals and processing powders. Pharmaceutical companies apply them in production to obtain specific grain sizes. The screens also separate unwanted material, e.g. oversize agglomerates during tablets manufacturing, lose control of processes, and improve the purity of final products.

• Catering & Food Service

  In the food industry, dry sift mesh screens are mainly useful for separating undesirable lumps from spices and flour. Bakery owners or chefs can use the screens to obtain specific grain sizes when producing items like custard powder, powdered sugar, cocoa flour, and cake flour. Screens with different mesh sizes are also useful when bottling oil to filter out undesirable sediment and stuff.

• Industrial applications

  In industrial settings like recycling plants, dry sift screens are useful for separating undesirable plastic types from productive ones, contaminants, and other materials. For example, when processing e-waste to recover valuable materials like gold, copper, and silver, adequate mesh screens are necessary to sieve and extract these precious metals. Similar applications of dry sift screens in industrial settings include grading and sieving agriculture products like crops and seeds and separating minerals.

How to choose dry sift screens

Before purchasing dry sift screens, buyers need to check the following aspects.

• Screen mesh size

  The mesh size is the first factor to consider when purchasing cannabis dry sift screens. The mesh sizes range from micro sized to larger sizes. Each mesh will allow different types of trichomes to pass through. Finer mesh sizes will filter out only the finest gland heads, while larger holes will let more plant material go through.

• Material durability

  Buyers need to choose the screens' fabric carefully based on the material and its durability. Screens made from stainless steel will not sag over time or with constant use. Their surface will be easy to clean, and they will produce a decent amount of kief. Stainless steel mesh screens are more durable than their nylon counterparts, which can easily tear and damage.

• Frame type

  The frame used in dry sift screens also affects product durability and screen tension. Buyers can choose wood frames, metal frames, or rigid mesh frames. Wooden frames are typically less expensive and will not corrode. However, they tend to warp over time. Metal frames offer a sturdy base that holds the mesh screen tightly. Rigid mesh frames have a flexible back that is easy to store.

• Functionality

  Variables like mesh materials, frame types, and mesh sizes will affect the functionality of the dry sift screens. So, buyers need to select the screens according to their functional needs. Compare the final product output and choose screens that can offer the desired function.

Dry sift screens FAQ

Q1: How do dry sift screens work?

A1: Dry sift screens work by allowing specific particles to pass through based on their size. The cannabis plant's trichomes are bubble-shaped, making them lighter than most plant materials. They then bounce around the mesh and exit through the holes, settling below in the collection tray. Other larger materials either get stuck in the mesh or above the screen.

Q2: What are dry sift screens made of?

A2: Traditionally, dry sift screens were available in fabric or nylon options. Nowadays, cannabis producers and retailers offer stainless steel dry sift screens in the market. They are more resilient and are easy to clean compared to the older models.

Q3: Do Dry Sift Screens are the same as screening meshes?

A3: No. sift meshes are made with particular kinds of threads to capture trichome particles. While they might look similar, their functionality is very different.

Q4: What is the difference between dry sift screens and wet screens?

A4: Wet screens are used for the water extraction method, which is screening cannabis compounds while using water. Typically, owners will use finer mesh screens and work their way to larger ones. The dry method only utilizes screens to separate the plant material from the trichomes.
