A bubble hash press is an invaluable tool for extracting cannabis concentrates. By applying heat and pressure, this powerful machine compresses trichome heads from buds before sifting them into coins or pucks for easy collection.
No matter the press you use - be it pneumatic or hydraulic - temperature and pressure are key ingredients of high-quality rosin production. For optimal yields, consider creating a homemade H-frame hydraulic hash press with rosin plates.
1. Hydraulic Jack
Hydraulic jacks are mechanical devices used to lift heavy loads. Their design includes a base fitted with a pump cylinder containing a lifting ram that reciprocates when activated by a handle; designed specifically to lift large vehicles, machinery, or elevators from low- to mid-rise buildings.
Hydraulic jacks are created through complex manufacturing processes requiring enormous energy expenditure. Their outer cylinder is fashioned out of solid metal stock while their free ends and vertical assembly have cast shapes given to fit precisely into receptacles in their base receptacles; self threading bolts extend through these receptacles from underneath to keep both pieces attached together.
As part of a DIY hash press, a hydraulic jack capable of supporting 2-8 tons is an essential component. To build one yourself, an aluminium sheet must be strong enough to withstand the force of the jack against it, before fabricating racks and stops that will secure the cylinder.
Based on your budget and requirements, purchasing a commercial hydraulic hash press may be preferable to making one yourself. While expensive, commercial presses offer consistent and precise hash pressing with their containment rings with pistons which press hash against plates under constant pressure in order to decarboxylate cannabinoids into smaller, rounder forms more quickly.
There are manual rosin presses that are user-operated without the use of compressed fluids, making them less costly while still producing great rosin results. These manual presses offer greater control and precision compared to their electric counterparts - ideal for home growers and artisan hash makers looking for precision manual operation.
Homemade hydraulic hash presses provide an economical alternative to commercial products for those with the skills and materials to create one. All that's necessary for creation of one includes an efficient jack capable of applying consistent pressure, aluminium sheet that can be welded without rusting, and strong clamps to hold down its platen when under pressure.
Your plates are the heart of a rosin press, as they must be heated to an exacting temperature to facilitate effective trichome extraction. Metal and ceramic varieties are commercially available; alternatively, homemade solutions could include using bookbinding presses or modified hair straitners as effective and more cost-effective options.
Whenever selecting the size of rosin plates for use, one should keep in mind the volume of bubble hash they wish to press at any one time. As volume increases, so too does pressure needed for compression; alternatively smaller sets may offer lower yields but higher quality results.
Once your plates are assembled, lightly coat them with cooking oil for extra rust protection and to use as a release agent when pressing. Also ensure they are perfectly aligned and spaced evenly before beginning pressing with plate two on top. Press hard with your jack.
Pressing rosin can be challenging, and over-straining your rig is the primary source of error. Overextending can result in blow-outs - when too much pressure has built up inside a bag and it ruptures open, leaking unfiltered rosin onto parchment paper - which significantly decreases both yield and quality, though they're easy to prevent with some simple steps.
Home-made rosin presses can be made by creating an H-frame out of aluminium and using heat resistant plates heated to precise temperatures to facilitate optimal extraction. However, this is an extremely complex and time consuming process; you would likely get better results by purchasing commercial hydraulic hash presses which provide similar results quicker.
Rosin plates come in both ceramic and metal varieties; metal is generally preferred due to its durability, longevity and consistent rosin quality. As well as having quality plates at your fingertips, you will require an appropriate-sized hydraulic jack capable of supporting the full weight of your press as well as an appropriate hydraulic pump with pressure-regulating capabilities and an electronic PID temperature controller.
Once you've assembled all the materials and tools necessary, the next step will be constructing your rosin press frame. Your frame should be constructed out of rigid material such as aluminium sheeting that can be welded together before being bent into shape into its final form - such as welding rod. Once your frame is finished, attaching rosin plates is next.
When using a rosin plate to stamp bubble hash, be mindful not to go straight for maximum pressure right away - gradual pressure increases will reduce rosin bag blowouts which could potentially lower yield and quality significantly.
For those wishing to avoid the trouble and expense of creating their own hydraulic hash press, there are other smaller devices which can be used with handheld kief collecting grinders. These small metal tubes with low torque T handles allow you to press against pieces of weed to extract trichomes before collecting and transfering to glass containers for dabbing.
4. Hydraulic Pump
A hydraulic pump transforms mechanical energy into hydraulic energy by forcing a piston to open and close a valve at variable speeds, while also transmitting that energy via its discharge valve to equipment or machinery. A hydraulic pump works according to Pascal's law which states that any increase in pressure at one point of liquid in equilibrium will be transferred evenly throughout its entirety.
Hydraulic hoses or tubes serve as conduits, transporting hydraulic fluid from its reservoir to various components within a system. To do their job effectively, these conduits must withstand high pressures while also being durable enough to avoid air bubbles and dissipate heat generated during operation.
Before selecting a hydraulic pump, the first thing to consider when choosing one for an application is what working pressure and piston stroke requirements exist for that application. If building a shovel requires large piston stroke with minimal power requirements; for a hydraulic press this means having small piston stroke with maximum output power requirements.
Hydraulic pump motors are typically rated according to maximum pressure and litre capacity per minute, providing useful data when comparing models as it allows one to gain insight into each motor's power and capacity. When choosing an electric motor it's important to remember that when operating under load they may produce additional power than their catalog rating allows.
Once you have selected a hydraulic pump, the next step should be creating or purchasing a reservoir for it. Fill it with either AW46 or Dexron III hydraulic fluid before using parts cleaner to flush it clean before installing your pump and connecting hoses - making sure to test its solenoid first!
Created using an old bookbinding press (plans can be found online), use a thick sturdy rod like an old bookbinding press to form the cylinder and add your plant material. Insert the rod, insert your plant material, hit with a hammer once and you should have your product set - press to set, portion out into pucks or even press into hash oil (Gray Wolf would know about this technique!). Pressed, you can make portioned keif pucks or even press your hash into hash oil (Gray Wolf would know about this technique)! Once pressed you can create portioned keif pucks - or press even hash oil (Gray Wolf told about this method!). Once pressed you can press your product into hash-oil (Gray Wolf has mentioned this method).
There are two basic types of rosin presses - hydraulic and manual. Hydraulic models use compressed fluids to generate pressure, making them generally simpler and more precise to use than manual models. They're also capable of applying greater force allowing for higher yields from smaller pieces of rosin.
To minimize blow-outs, ensure your rosin bags aren't overfilled, sealed tight and preheated before beginning to apply pressure. Apply light pressure initially and gradually increase it as necessary; this will help avoid sudden rupture of the bag that would result in spilled rosin dripping out and losing valuable inventory.
Remembering the fact that bubble hash requires additional pressure than ice water hash can also reduce blowouts; thus if using a small home rosin press for making bubble hash it would be wiser to choose larger plates which can accommodate more rosin at one time; in addition, you may even find smaller presses specifically designed to work with handheld kief collecting grinders.
