R4 Wood Kernel

[Boyan Atanaschev]

Withinthe entire range of Trigonos construction games, Kernel is the set with the exact number of pieces to build a wooden house like the one in the main picture; no pieces left afterwards. However, kids can also let themselves go to open-ended play and imagination by building a ship, a puppet theater, a shop... Can you imagine what other structures they can build? Will you stop yourself from being part of this?

Kernel is an ideal wooden construction game for pretend play for kids starting at the age of 4. But it can also be used at a later age for geometric, mathematical and construction challenges covering various stages of children's play or as a manipulative material (around 7-10 years old). It is therefore a child development game.

Its stick and block-based system allows kids to simply assemble and disassemble structures on their own as many times as they want. Sticks can be easily inserted into the block holes to create a stable structure where they can play and enjoy themselves. Fabrics have a hem through which sticks are inserted, so that they all stand well fixed and tense to create well marked out areas. However, the wooden pieces can be combined with other fabrics and wooden play clips to invent new and unique designs.

One of the advantages of this construction game is how easy it can be disassembled since despite taking up considerable room when assembled and producing structures you can go inside and hide, it fits in a much smaller space once disassembled. Kernel comes with a storage cardboard box to hold all the pieces in, thus minimizing space an awful lot. Additionally, though, we also provide a more solid and beautiful wooden box to store all the pieces inside.

The PKS(Palm Kernel Shell) is a by-product from the palm oil industry. It is the kernel shell of the oil palm fruit. In the palm oil press the palm kernel shell is separated from the kernel and become biomass residue. Now making palm kernel shell pellets is becoming hot in pellet making industry in Southeast Asia and European countries. Our ring die wood pellet mill has outstanding performance in making solid PKS pellets due to its rigid design and gear transmission system.

Why choose palm kernel shell to make biofuel pellets?

Easy handling, easy crushing, the palm kernel shells are a fibrous material with a relative small size. Its moisture content is between 11% and 13%, lower than general biomass material. Because of the residue palm oil, the heating value of palm kernel shells is slightly higher than the lignocellulosic biomass. The palm kernel shell is widely existed in Malaysia, Indonesia, Thailand,Japan, Korea and some Europe countries. High solid content, high calorific value, low ash and low sulfur content, Palm kernel shell is your best choice for biofuel pellet production line!

Parameter of the Palm Kernel Shell

1. The palm kernel shell pellets can be used to replace fossil fuel and electricity for home heating

2. Partly or entirely applying PKS pellets to supplant coal in industry boiler

3. The PKS pellets can be burnt in the power plant in the high-efficiency CHP systems to generate electricity

4. Applying the high-pressure boilers to avoid incomplete combustion and the release of dark smoke

Remarkable Advantages of the PKS Pellets

*Palm kernel shell pellets is with low moisture in nature

*The PKS pellet is high in heating energy and efficiency

*Palm kernel shell pellets are easy to handle and store

*The PKS pellets are easy to control and have a broad application

*Palm kernel shell pellet is suitable for most boiler grating system

*PKS pellets generate low to no smoke during the combustion

We are proud to bring you an alternative to those high home heating bills. Our wood pellets have a strong reputation for excellent burn times. Stock up now and be ready for whatever the weather brings!

Near infrared diffuse reflectance spectra collected in 10-mm sections were used for the estimation of air-dry density (AD), microfibril angle (MFA), stiffness (MOE), tracheid coarseness (COARS), and tracheid wall thickness (WTHICK) in wood radial strip samples obtained at breast height (1.4 m) from 60 Pinus taeda trees. Calibration models were developed using traditional partial least squares (PLS) and kernel regression. The kernel methods included radial basis functions-partial least squares (RBF-PLS) and least-squares support vector machines (LS-SVM). RBF-PLS and LS-SVM models outperformed PLS-CV calibrations in terms of fit statistics. MFA and MOE, two properties that exhibited nonlinearity, showed the most significant improvements compared to PLS. In terms of predictive ability RBF-PLS performed better than PLS for the prediction of MFA, MOE, and COARS. LS-SVM showed better prediction statistics in all cases, except for WTHICK that gave similar statistics compared to PLS and was superior to RBF-PLS. By adding statistically significant factors to the PLS regressions, it was possible to capture some of the nonlinear features of the data and improve the predictive ability of the PLS models.

Concerns for the environment and for human health have become critical factors that motivate creating bio-based wood adhesives. Therefore, this study proposes replacing toxic chemicals with alternative adhesives. In the first step, glycerol was added to the natural phenolic compounds from liquefaction of palm kernel shell (PKS), having a high content of lignin. The obtained glycerol-based liquefied PKS, and its blend with citric acid, were tested for bonding in a study on the effects of hot-pressing conditions (temperature and time). The results revealed that the liquefaction system in this study achieved an 83% conversion of the PKS components into glycerol-based liquefaction. According to the Fourier transform infrared and carbon-13 nuclear magnetic resonance analyses, the glycerol-based PKS contained lignin derivatives and furan products. This accounted for its great performance in bonding rubberwood veneers. The tensile shear strength was improved by blending with 15% citric acid, especially when applying the high 190 C pressing temperature for 15 min.

Media blasting makes removing stain from log and wood structures easier and faster than ever. Because it uses only dry media, no water is forced into the wood. Dry time is eliminated, risk of rot, mold and mildew is reduced, and stains, chinking and caulking can be applied immediately afterwards. Stop playing the waiting game and get prep done faster.

Rotary dryers are used to dry small, powdery or granular wet materials such as wood chips, sawdust, sand, mineral dust, agricultural waste, etc. The raw material is transported by the scraper conveyor to the inside of the rotary dryer.and the front is equipped with a hot blast stove.

The generated hot air enters the dryer by the fire separating device, and the material is dispersed by the low-speed rotation and bending plate.so that the high-temperature airflow passes through the material and make heat exchange, the rotary dryer has a certain angle of inclination, and sufficient air volume to drive the material forward.Finally, the dried material is discharged from the discharge port.
