Roots of Taraxacum kok-saghyz (TKS) are a promising alternative source of natural rubber latex (NRL). This study demonstrated the novel possibility of extracting, stabilizing, and concentrating NRL from roots of TKS with a high solid content. In addition, some colloidal characteristics of the isolated products, which are of interest for latex processing, were determined. A scaled-up extraction sequence based on previous studies of flow extraction was applied with a setup comprised of an industrial slicer, stirring stations, and a hydraulic press. Significant amounts of natural rubber (NR) were separated along with removed biomass. Stabilization of NRL was successfully maintained during latex isolation using ammonia-free stabilizing solutions consisting of an ethanolamine/ethanolamine hydrochloride (ETA/ETA-HCl) buffer, sodium oleate, sodium sulfite, and benzalkonium chloride. Purified and preconcentrated raw latex was obtained through repeated creaming and redilution. While a direct further concentration of raw latex proved difficult, the isolation of latex with a high solid content was achieved through redilution before the final centrifugation. Gravimetry indicated a solid content of >54%. The products were characterized by a high viscosity, and dilution was possible without coagulation. ζ-potential (ZP) was determined to be −60 mV and approved the successful stabilization of high solid latex. Dynamic light scattering (DLS) confirmed the possibility of maintaining a bimodal particle size distribution (PSD) with hydrodynamic diameters of 104–231 nm for the first mode and 522–830 nm for the second mode.

“…A portable rubber tapping machine is a hand-held device, which can be easily deployed in plantations. As shown in Figure 5b, the use of the 4GXJ (Rubber Research Institute, Chinese Academy of Tropical Agricultural Science) electrical tapping device, a kind of portable electrical tapping device driven by electricity, can decrease the labor intensity of rubber workers [51]. Because of its poor levels of automation, it is preferable to use it as an auxiliary device [52].…”

The Development of Rubber Tapping Machines in Intelligent Agriculture: A Review

et al. 2022

In the past decade, intelligent technologies have advanced rapidly, particularly due to improvements in automatic control, which have had a significant impact on forestry, as well as animal husbandry and the future of farm management. However, the degree of production and management mechanization in natural rubber plantations is low, especially since the methods of tapping still rely heavily on labor. The decrease of skilled rubber tappers and the increase in labor costs have led to the development of the mechanization of rubber tapping operations. The application of emerging intelligent agricultural technologies could provide an alternative in order to maximize the potential productivity of natural rubber. Based on this vision, we reviewed the literature on rubber tapping from the past decade for system implementation in rubber plantations. In this review, selected references on rubber tapping were categorized into several directions of research, including rubber tapping machines, the key technologies applied in tapping operations, and some related protective research, analyzing research works from 2010 to 2022 that focused on tapping methods. The review also discusses the application of intelligent agricultural technologies, such as the recognition of tapping trajectory and tapping path planning. A summary of challenges and future trends is also provided in this study. Based on the relevant research, the use of intelligent technologies in rubber tapping machines is still in its initial stage and has broad prospects. Through this study, we aim to provide a reference for researchers in the field of rubber tapping machines and thus to play a positive role in future rubber tapping.

A novel NPRBDD is developed to obtain suitable cutting depth of rubber bark in the harvesting process of natural rubber. Based on experimental data and the optical microscope photographs of slice diagram of the pinhole in rubber bark, the acupuncture-detection process of NPRBDD can be divided into three stages of pre puncture stage, squeezing stage and puncture stage. The main bending deformation of probe occurs in the squeezing stage, which will affect the detection accuracy of NPRBDD. Regarding the motion characteristics of the probe in the squeezing stage, a new expression of finite element method are proposed and used to establish nonlinear dynamic variational equations of probe. And a fractional order model was used to fit the force on the probe tip. According to numerical simulation, the probe of NPRBDD is selected that stainless-steel-316L probe with 25mm length and 0.25mm radius. Then, through field experiments, the validity of NPRBDD is validated, and it can be found that the stability of detection result of NPRBDD is higher than that of traditional measurements.
